Hoosier Life Survey Summary Report

Preparing for Environmental Change in Indiana: The Hoosier Life Survey

Note: For descriptions of charts published in this report, contact ERI at eri@iu.edu or 812-855-8539.

Environmental changes such as extreme weather events, rising temperatures, floods, or droughts affect people across the globe. But whatever their source and however great their extent, these conditions also touch us at local levels that we experience each day—around the house, across our community, on the farm, and throughout the state where we live.

The global challenge of environmental change is an Indiana challenge, too.

What is the Hoosier Life Survey?

The Hoosier Life Survey (HLS) is the nation’s most comprehensive statewide public-opinion survey of environmental change to date. The HLS addresses how environmental changes—particularly extreme weather events—are perceived, how they affect people in their homes and towns, what Hoosiers are doing about it, and what they expect for the future. This research, sponsored by Indiana University’s Environmental Resilience Institute (ERI), was funded by IU’s Prepared for Environmental Change Grand Challenge initiative.

Between August and December 2019, ERI reached out to 10,000 adult (18+) Hoosiers across Indiana—from Chicago’s suburbs to Cincinnati’s metropolitan fringe, from the Grand Chain of the Wabash to the shore of northern Indiana’s historic Limberlost Swamp. In total, 2,739 Hoosiers—representing 90 of the state’s 92 counties—responded. Thanks to their participation, ERI can now offer scientists, public officials, and the general public new insight into how climate change affects Hoosiers in their everyday lives. (See Appendix 1 for a more detailed description of the survey methods. After dropping respondents from our sample who did not fill out all of the questions examined in this report, our findings below draw on the responses of 1,500 Hoosiers from across the state.)

What does the HLS tell us?

We asked our Indiana neighbors more than 100 questions, organized in sections titled Who You Are, Where You Live, What You Value, What You’ve Heard, You and the Environment, and What You Do. Taken together, our respondents’ answers show us what Hoosiers think about environmental change—its origins, its extent, its impact on their families. The survey tells us, too, how Hoosiers learn about the issuesvital to their future—whom they trust, to whom they listen, from whom they’d like to hear more. It highlights how much Indiana residents are already doing—or are prepared to do—to build resilience in the face of one of the grand challenges of our time. And it reveals the role of political and personal values—along with social, demographic, and economic differences—in dividing Indiana’s citizensin their approach to that challenge—as well as the fundamental things that we share despite such differences.

HLS’s in-depth, localized data enrich and focus the findings of other studies such as the Yale Climate Opinion Maps or the Pew Research Center's US Public Views on Climate and Energy report. While these national surveys provide useful guidance to Americans seeking to understand and prepare for environmental change, the HLS—combined with the ERI's Hoosier Resilience Index, ERI Toolkit, and the Indiana Climate Change Impacts Assessment, coordinated by the Purdue Climate Change Research Center—provides a model for universities and states wishing to tailor their understanding of environmental change and resilience strategies to the particular geographies and political and social settings in which practical, local actions can be taken.

What have we learned so far? Highlights of the HLS

In the sections that follow, we highlight some statewide findings about Hoosier responses to environmental change and extreme weather events. Look for more detailed analysis of these and other results in the months to come.

What You’ve Heard

How informed do Hoosiers feel?

We asked Hoosiers how well-informed they feel about the risks from extreme weather, a key impact of climate change, and the strategies or solutions needed to face them. While most respondents have some idea of what changes in household practice or public policy might improve resilience, they told us that they feel better-informed about the facts of climate-related problems than they do about how to respond to those challenges (Figure 1).

Figure 1: Few Hoosiers feel well informed about how to prepare for climate-related extreme weather events
*Question: How well-informed do you feel about the following?*
Response options	Extreme weather events that may affect me or my family	Household practices to reduce risks from extreme weather events	Programs or policies that can reduce the risks future extreme weather
Not at all informed	3%	7%	17%
Slightly informed	16%	31%	40%
Moderately informed	54%	47%	34%
Very informed	28%	16%	10%

SPOTLIGHT: The role of age in shaping how informed Hoosiers feel about extreme weather

While most Hoosiers do not feel “very informed” about the risks associated with weather extremes and even fewer feel “very informed” about how to prepare for these events, there are some clear differences in who feels this way among Indiana residents. Older Hoosiers are more likely than younger Hoosiers to feel very informed about these risks and the policies to deal with them (Figure 2).

Moving forward, it will be important to determine if older Hoosiers are actually accurately informed about the risks from extreme weather events, as many extremes to come (such as greater frequency and intensity of heat waves) pose a more significant risk to older individuals. Given that fewer older Hoosiers feel very informed about how to deal with extreme events, more outreach and resources may be needed to help this already vulnerable population prepare.

Whom do Hoosiers trust?

We asked Hoosiers whom they trusted to provide reliable information on how to prepare for the impact of extreme weather events. They registered their highest level of distrust toward local officials; their highest level of trust, by far, lay in their own judgment. Scientific communities comprised their next most trusted source of information on how to prepare for future climate impacts, followed by family, friends and neighbors, and the media (see Figure 3).

Figure 3: Hoosiers most trust their own judgment, and then scientists, when it comes to getting information about preparing for extreme weather

SPOTLIGHT: Community type of trust in information sources

Whom Hoosiers trust for information about how to prepare for the impacts of climate change, such as extreme weather events, will shape how or even if they prepare.

Individuals we surveyed who identified their community as “urban” were much more likely to trust scientists “a lot” for information about how to prepare for the impacts of extreme weather than those in rural areas. “Rural” and “urban” Hoosiers were both more likely than suburban and small-town Hoosiers to trust their “own judgment” a lot. These results suggest that expert-driven outreach may be an effective way to connect urban residents with resilience planning information, but be less influential in rural communities. Efforts that allow rural residents make up their own mind, such as connecting with local stakeholders or holding community meetings or dialogues, may be more a impactful form of outreach with residents of rural communities.

You and the Environment

Beliefs about climate change

Most Hoosiers believe that climate change is happening—both from their own experience and from what they understand as the scientific consensus. They are less unified in their assessment of the source of this change—whether it comes from natural, human, or some combination of natural and human causes. Roughly eight out of ten of those who believe that the climate is changing also believe that this change is at least to some extent related to human activity. Yet, as figure 6 shows, not all of those who see human activity as playing a role in climate change believe our actions are the primary cause.

SPOTLIGHT: Climate change in the media and Hoosiers’ awareness of scientific consensus

Over 97 percent of climate scientists agree climate change is happening and caused by humans (Cook et al. 2016). Yet, nearly one-third of Hoosiers perceive much disagreement among scientists (Figure 7). Hearing about climate change more frequently appears to be associated with being more likely to correctly recognize scientific consensus (Figure 8).

This finding may suggest that greater communication and outreach efforts could encourage more widespread recognition of the reality of the climate crisis.

What impacts are Hoosiers experiencing?

We wanted to know whether and how Hoosiers have directly experienced a range of symptoms of extreme weather or environmental change. We found that, while nearly 80 percent of Hoosiers believe climate change is occurring, relatively few feel that they have witnessed such changes within their own communities (Figure 9). This contrast suggests that perceived personal experience is not the dominant driver of belief in the occurrence of climate change. Overall, most of our respondents think that such conditions have remained about the same in their own area; a small percentage of respondents believe that they have even decreased. We also note that Hoosiers have observed the rise of a few particular symptoms of environmental change more than others: around 30 percent of our survey-takers identified heat waves, heavy rains, or mosquitoes as having increased in their own communities. Interestingly, almost 30 percent of Hoosiers also reported an increase in extreme cold temperatures, which is contradicted by evidence showing that the occurrence of cold events has declined since 1915 (Widhalm et al. 2018).

What impacts are Hoosiers anticipating?

We asked our respondents if they think that their communities will be affected by severe climate stresses in the coming decades. Very few Hoosiers felt that climate change-related impacts will decrease in the future. The two adverse conditions that respondents identified as more likely to increase than simply to stay about the same are the incidence of heat waves and the presence of mosquitoes and ticks (Figure 10).

SPOTLIGHT: Climate change beliefs and expectations for future changes

What Hoosiers expect to come in the future may shape how they choose to prepare today. While many in Indiana anticipate that the accelerating impacts of climate change will touch their community, individuals’ beliefs about climate change shape the extent to which they anticipate these impacts.

In figure 11, we show that Hoosiers who do not believe climate change is occurring now, or those who do not feel it is caused by human activity to any extent, are much less likely to anticipate future climate change-related impacts. Interestingly, Hoosiers' expectations for greater prevalence of tick and mosquito-related disease were not as tied to climate change beliefs as expectations for other changes.

*Percentage saying each impact "will increase" in their community in the future*

What crises are Hoosiers anticipating?

We asked survey respondents how likely, in their estimation, it was that within the next decade that their family’s well-being would be impacted by a variety of major events: extreme weather, government shutdown, economic crisis or major disease outbreak. Economic crisis (23 percent) and government shutdown (21 percent) were the events that respondents were most likely to feel were “very likely” to impact them in this timeframe. It is also clear that when our respondents received their surveys in the fall of 2019, few were anticipating that in only a few months the world would experience the spread of a deadly virus such as COVID-19. Indeed, a major disease outbreak was the event least anticipated by our respondents. Over half (52 percent) of the Hoosiers we surveyed felt it was “unlikely’ or “very unlikely” that a major disease outbreak would impact them in the next decade (results not shown), with only 4 percent of the state feeling this type of event was “very likely” to harm them (Figure 12).

SPOTLIGHT: COVID-19 and Hoosiers’ expectations about future crises

At the time of this report, COVID-19 has been particularly impactful on major cities across the United States, including Indianapolis. Despite being Indiana’s current epicenter for the disease’s outbreak, our results suggest that when compared with residents of other cities, towns, and regions of the state, Indianapolis residents were on average the less likely to expect their family’s lives to be impacted by a major disease outbreak over the next 10 years (Figure 13).

However, upon a closer look, we see a stark divide based on household income among the city’s residents. Lower-income Hoosiers living in Indianapolis, defined by earning $0-$44,999 annually, were more likely to expect to be harmed by a major disease outbreak than those in the same income bracket who lived in other areas of the state (27 percent to 19 percent respectively, Figure 14). In contrast, respondents in middle-to-high income households in Indianapolis were less likely than those in other regions with the same income to expect this event (10 percent compared to 18 percent respectively). As some recent evidence suggests, lower-income individuals are more at risk from COVID-19 for a variety of reasons (Mansoor, 2020). Our results imply that, in Indiana and especially Indianapolis, lower-income individuals were also more likely to expect to suffer from this type of crises, among other impacts (see also figure 18).

How concerned are Hoosiers?

A majority of Hoosiers anticipate that climate change will harm the people, plants, and animals of Indiana. Most agree, too, that climate change is already adversely affecting other Americans (Figure 15). Almost 30 percent believe that these changes will affect the people of Indiana a “great deal,” with only around 15 percent believing that they will be personally harmed “a great deal” (Figure 16). Few tend to believe that the majority of Hoosiers in their community are concerned about the potential dangers of extreme weather events (Figure 17).

SPOTLIGHT: Income and perceived risk from climate change

Lower-income households are among the most at-risk from climate change. Limited economic resources constrain their capacity to adapt their homes or lifestyles to new risks, and often they are already more exposed to environmental risks, such as pollution from industrial production (Tol et al. 2004).

Perhaps reflecting these circumstances, Hoosiers in lower-income households are more likely to perceive that climate change will harm them personally a “great deal” than those in high-income households (Figure 18). Lower-income populations, therefore, may require less emphasis on the need to prepare for climate change and
could benefit from programs and policies that provide resources which enable these communities to act on their already higher level of personal concern.

What do Hoosiers believe is possible and effective?

Hoosiers’ responses to environmental change will be shaped by what they consider to be possible. Only a minority (26 percent) of our respondents agree that humans can “do little” to prepare for extreme weather effects. A majority believe that public policy (53 percent) and unspecified “simple things” (52 percent) have the potential to mitigate the impact of these risks upon their communities and themselves (Figure 19).

What You Do

Are Hoosiers taking action at home?

We looked at people’s household responses to the impact of adverse climate conditions, asking both what they currently do and what they might like to do in the future. Their answers reveal that some basic practices for reducing energy consumption and mitigating the impact of heat and cold, such as use of shade trees, improved insulation, and high-efficiency light bulbs, are already in common use (Figure 20 and 21). Other practices, such as installation of solar panels, registered significant interest among Hoosiers as a potential future household activity (Figure 21).

SPOTLIGHT: Rural Hoosiers and interest in solar panels

Solar panels are a key means to reduce emissions from homes, while also providing greater resilience to the potential increase in severe storm-related power outages in the Midwest. Despite the fact that rural Hoosiers were less than half as likely as urban Hoosiers to believe climate change is caused by humans (22 percent versus 43 percent respectively), they were roughly equally likely to have installed or currently wish to install solar panels on their homes. Importantly, the question specified that the solar panels would “reduce carbon dioxide emissions” (Figure 22).

Whether rural residents specifically wanted to use solar panels for this reason or desired to add them for a different benefit, such as energy independence or lower power-costs, is unclear at this time. What this finding does suggest is that people across the state want to add solar panels—even those in rural areas who may not hold views about climate change that accord with scientific evidence. Policy that supports this effort could have significant impacts in terms of reducing Indiana’s greenhouse gas emissions and increasing the resilience of our energy grid.

Do Hoosiers perceive others in their community to be acting?

Despite the commonness of people’s reported efforts (or desires) to improve their home’s resilience in the face of a changing climate, only a very limited number of Hoosiers (6 percent) assumed that “most” other residents of their communities had taken the same precautions, and the majority (75 percent) perceived that the number of their neighbors taking these actions was not increasing (Figure 23).

What climate-related programs and policies do Hoosiers support?

Beyond the level of particular household practices, Hoosiers also offered their thoughts on the efficacy of wider-scale efforts to prepare for extreme weather events. Given a wide range of options toward which to apply hypothetical tax dollars, HLS respondents favored a combination of conservation-oriented measures (such as replacing paved areas with water-absorbent landscapes) and engineering-based solutions, such as building higher floodwalls to prevent flooding or extending additional pipelines to minimize the impact of drought. In other words, a significant number of Hoosiers tend to favor some government assistance in ameliorating the adverse impacts of environmental change—but respondents show no clear preference for solutions that may favor long-term resilience over shorter-term relief. Below, in figure 24, we categorize the survey’s proposed policies and programs by two groups: Short-term fixes and long-term solutions. Short-term fixes, as the name implies, provide risk-reduction benefits, but likely increase future risks by accelerating environmental harms or failing to alter key risky behaviors. Many long-term solutions may be harder to implement, but ultimately provide greater resilience in that they promote changes to our existing, environmentally harmful behavior. At this point, we cannot conclude there are any differences in Hoosiers’ support for resilience policy and practices based on these categories.

Who should pay for climate policy in Indiana?

Because all of the above questions assumed the existence of public funds, we also asked our survey respondents who they thought should bear the cost of such initiatives (Figure 25). Nearly half said that such funds could be levied in the form of a statewide income tax increase of up to 1 percent. Well over half reported that they would support such a tax—if it were levied solely on households earning more than $165,000 per year (roughly three times the state’s current median household income). And a greater majority, still, said that they would favor such a tax if it were levied specifically on corporations, in proportion to the degree to which they are responsible for emissions of pollution. Yet despite these signs of statewide support, we found that only 7 percent of Hoosiers felt that “most” of their fellow community members would be likely to support additional tax levies earmarked for the purpose of addressing climate risk, and half reported they “don’t know” how their community feels about these taxes. This contrast may suggest that many in Indiana are not discussing these issues with their neighbors. Similarly, the vast majority of respondents (72 percent) felt the number of their community members supportive of these taxes was not changing (Figure 26).

SPOTLIGHT: Politics and Taxes

Political ideology is among the most significant factors shaping how Americans view the issue of climate change (McCright et al. 2016). While this fact remains true among Hoosiers and in our data, some measures to address weather extremes receive majority support from the public regardless of their personal politics.

Addressing climate change, and its impacts, requires state-level action and likely new revenue streams to fund these actions. Toward this end, the majority of Hoosiers from all political affiliations—when faced with a situation that demanded increased public funding—supported raising a tax on businesses based on the amount of pollution they create (Figure 27). This should not be viewed as a question about the viability of the policy so much as it is a way of gauging the relative support for who Hoosiers feel should pay for addressing environmental risks in the state.

In coming months—through public appearances, news features, media releases, and scholarly studies—the HLS team will provide additional detail from the survey responses and continue to highlight insights and provoke further research into how Indiana residents, scientists, businesses, and public officials can work together to build resilient communities. Scientists predict that over the next 50 years our state’s average temperature will increase by 5°F to 6°F. Additionally, we will see more frequent and intense precipitation events, leading to more flooding, especially in the spring. Some areas of the state could see up to a six-fold increase in the number of extremely hot days (over 95°F) in the next 30 years (Widhalm et al. 2018). You can find complete survey results—and tailor them to address the questions that most interest you and your neighbors—on our interactive website, https://eri.iu.edu/tools-and-resources/hoosier-life-survey-opinion-map.html.

Appendix 1: Methods

The survey from which data for this report were drawn was sent out to 10,000 Hoosiers between August and December 2019. The survey focused on gathering a broad range of information related to Indiana residents’ views of their community, environmental changes and risk, climate change beliefs, the household- and community-level actions they were taking or supported being pursued, and their personal values. Surveys were sent to Indiana households using a spatially stratified sampling approach. To ensure adequate coverage of people across the entire state and for later geographically specific analysis, our team developed eight in-state regions, defined by clusters of counties. Each of Indiana’s 92 counties was included in a region. From each region, 1,250 home addresses were drawn at random from the United States Postal Service’s list (for a total of 10,000), which was purchased from a private address-based sampling vendor.

In mailing surveys to these households, a modified Dillman approach was used with a total of five mailing-waves (Dillman, Smyth, & Christian, 2014). In an initial wave of mailings, households received a cover letter informing them about the survey, noting the confidentially of their responses and asking them to fill out the survey online. A link to the online survey and user ID number were provided in the cover letter. Roughly two weeks later, a reminder postcard was sent to all sampled individuals who had yet to respond. After approximately another two-week period, respondents who had yet to fill out the survey online were sent a paper booklet version of the survey and another cover letter requesting their participation. A final mailing wave, containing another booklet and cover letter, was sent to all remaining non-participants after another two-week period. Both the initial contact for the web-based survey and the mail-based version contained $2 pre-incentive payments. Upon completing the survey, respondents could request a $20 Amazon or Walmart gift card. In total, our response rate was just over 27 percent. Case-wise deletion analysis was used to address missing data in this report, resulting in 1,500 cases being examined. Patterns of missing data were explored, as were relationships between missing responses and key demographics. No consistent patterns emerged, nor were strong relationships identified. In terms of differences between the full and complete samples, average age of respondents was the only significantly different demographic variable (average of 51 versus 50 years old, respectively). In consequence, this data may slightly over-represent younger respondents. Future HLS reports and data products may use data imputation methods depending on analysis type and the variables of interest. There is also the potential for some bias introduced bias the question design.

To ensure accurate population estimates for this analysis, survey weights were used. Weighting incorporates: (1) a base weight adjustment for unequal probabilities of selection due to disproportionate stratified sampling by region and due to the number of adults in the household, (2) a differential nonresponse adjustment to correct for unequal response rates by stratum/region, and (3) a calibration adjustment to 2018 American Community Survey estimates on gender, age, education, race, and Hispanic origin in the Indiana adult population. Weights were trimmed and scaled to the unweighted number of respondents.
