Overview of Idaho

GEOGRAPHY

Idaho is a large western state with impressive mountain ranges, large areas of high desert and massive expanses of forested terrain. Geography and distance impact both the demographic characteristics and social determinants of health within Idaho.

Idaho is ranked 38th of the 50 United States for total population and 14th for geographic size. The 2022 census population for Idaho was 1,939,033 and, because of its large size and relatively small population, Idaho remains one of the most rural states in the nation. With approximately 22.3 people per square mile, Idaho ranks 44th of the 50 states in population density. Thirty-five of Idaho’s 44 counties are rural, with 16 of these considered remote, which means those counties have fewer than six people per square mile.

PEOPLE

The 2020 census diversity index shows that racial and ethnic diversity has increased in Idaho over the past decade. In 2020 the diversity index from Idaho was 35.9 percent, up from 28.2 percent in 2010. A diversity index of 0 percent would mean that everyone in the population has the same racial and ethnic characteristics, while a value close to 100 percent indicates that everyone in the population has different racial and ethnic characteristics. The diversity index for the United States was 65 percent in 2021, up from 54.9 percent in 2010.

Persons of Hispanic or Latino origin comprised 13.3 percent of Idaho’s total 2021 population and could be of any racial group. Idaho is home to six federally recognized tribes: Coeur d’Alene Tribe, Kootenai Tribe of Idaho, Nez Perce Tribe, Shoshone-Bannock Tribes of the Fort Hall Reservation, the Northwestern Band of the Shoshone Nation and the Shoshone-Paiute Tribes of the Duck Valley Reservation. Idaho also has two refugee centers located in southwest Idaho (Ada County) and south-central Idaho (Twin Falls County).

SOCIAL DETERMINANTS

 

The conditions in which people are born, live, learn, work and play have a substantial impact on health outcomes and quality of life. Also known as the social determinants of health (SDOH), these conditions and the policies and systems that shape them, are the underlying, contributing factors of health inequities that result in differences in health outcomes for some populations.  SDOH factors include income, education, housing, safe environment, access to healthy food, quality health care, social support, discrimination, and other factors that influence health choices, behaviors, and opportunities.

Social, economic, and environmental factors and their influence on health can vary greatly depending on where one lives, as each neighborhood has differing levels of access to affordable housing, good jobs, healthy food, education, and healthcare. In Idaho, mapping life expectancy by county shows a difference of as much as 10 years of life between the highest and lowest counties. In Benewah County life expectancy is 74.8 years compared to 85.2 years in Blaine County. Even greater disparities are seen at the census tract level.

  • Economic Stability
    Poverty is a strong predictor of poor health. According to the 2021 American Community 1-Year Survey (ACS), the median household income was $66,474 in Idaho compared to $69,717 nationally.[i] Similarly, per capita income was less in Idaho at $33,841, compared to $38,332 nationally. All racial and ethnic groups measured in the ACS had lower household and per capita incomes in Idaho than their counterparts nationally. Despite lower incomes, Idaho’s overall poverty level of 11 percent is lower than the national average of 12.8 percent and has been decreasing.[ii] Within Idaho, poverty has decreased from 2016 to 2021 in all racial groups and among the Hispanic and Latino population (2016 & 2021 5-year ACS). Regardless of the overall improvements, disparities do still exist among demographic groups and within certain areas. For instance, 24.6 percent of Black or African Americans, 25.8 percent of Native Americans and 16.6 percent of Idaho’s Hispanic or Latino population is estimated to live at or below the poverty level in comparison to 10.6 percent of the white population who do not identify as Hispanic or Latino. Geographic disparities exist across the state with poverty measured at the county level ranging from 24.3 percent in Madison County to 5.2 percent in Clark County [iii]. Access Limited Income Constrained Employed (ALICE) – in Idaho, ALICE identifies and defines those households who fall within the “gap” – though they have income above the Federal Poverty Level (FPL), they are ineligible for state or Federal benefits programs and struggle to make enough to support their families. According to UnitedforALICE.org, ALICE families are often forced to make difficult decisions when they don’t have enough income to afford basic needs - housing, food, transportation, childcare, and health care. These decisions mean a family must decide between paying the rent or paying their childcare provider, or between buying groceries and filling a prescription. In 2021, the most recent ALICE data available, 11 percent of Idahoans fell under the FPL, while another 32 percent were ALICE. As Idaho’s cost of living rises, driven by the skyrocketing growth in housing prices outpacing growth in wages, more households are finding their financial stability jeopardized.[iii] Idaho’s low wages coupled with rising costs of living across the state has resulted in many wage-earners struggling to get out of poverty. The economic impact of COVID-19 on Idaho’s economy and people is still being realized. [i]. U.S. Census Bureau.

  • Education
    Education and income go hand-in-hand. “A quality education is the best predictor of professional and financial success in the U.S., and the earliest years of a child’s education lay a critical foundation for this success.” Quality early education increases the likelihood of children who are prepared for kindergarten, graduate from high school, achieve higher education degrees and future career success. Additionally, people with more education tend to have higher incomes and better health outcomes. College graduates are often able to secure better paying jobs with fewer safety hazards and income from these jobs can be used on higher quality housing as well as other health enhancing resources.[i] A greater percentage of Idahoans over the age of 25 have graduated from high school (91.2 percent) than the national average of 88.9 percent.[ii] Yet, the rate for those who go on to higher levels of education are lower in Idaho across most demographic groups. Nationally, 33.7 percent of the population over the age of 25 hold a bachelor’s degree or higher, while 29.1 percent do in Idaho. Educational attainment disparities are also seen among various racial and ethnic groups. For Idaho’s Hispanic and Latino population, 67.5 percent are high school graduates or higher compared to 71.2 percent nationally.[ii] Also, 13.4 percent of Idaho’s Hispanic and Latino population holds a bachelor’s degree or higher compared to 18.4 percent across the U.S. Within Idaho’s rural and remote counties, a smaller percentage of adults over the age of 25 have gone on to receive at least some post-secondary education than those living in urban counties, 55.4 percent compared to 67.6 percent.[ii] Quality and affordable early childhood education is a vital component necessary to support a child’s lifelong educational attainment and future earnings. In turn, access to affordable childcare supports a healthy economy as it allows parents to go to work and earn a better living. The most recent United for ALICE report, released by the United Way in 2023, highlights the crisis in child care availability and cost that was brought to the forefront in the pandemic. Many childcare providers went out of business during the pandemic and 35 percent of that workforce has an income below the ALICE threshold. While childcare providers are struggling to stay afloat families are also challenged with cost as a family of four in Idaho can expect to spend $1,137 on childcare each month. [iii] [i].

  • Neighborhood and Built Environment
    Community design and the quality of our built environments directly affect human health. The built environment refers to the physical spaces where we live, recreate and work. It is comprised of our homes, businesses, cultural institutions, parks, public spaces, roads, environmental conditions, utilities and other infrastructure. These neighborhood or community attributes have a profound impact on our health by promoting or restricting access to physical activity, transportation options, healthy foods, safe housing, and even social interactions. Research has shown that people living in more affluent neighborhoods tend to have better access to health promoting attributes like parks and safe connected sidewalks and pathways that are buffered from automobile traffic.[i] In contrast, people living in lower income neighborhoods tend to be exposed to unhealthy attributes such as higher levels of pollution from nearby freeways or industrial land uses. Emerging climate research also shows that residents living in lower income urban neighborhoods are exposed to higher summertime temperatures due to built environment conditions that include greater expanses of asphalt and concrete with fewer trees or green spaces.[ii] FOOD SECURITY Food security means “access by all people at all times to enough food for an active, healthy life.” Food insecurity indicates a limited ability to secure adequate food due to insufficient resources.[iii] Prior to COVID-19, Idaho was seeing improvements in the number of food insecure households. Data from Feeding America reported 8.7 percent of Idaho’s population faced food insecurity in 2020.[iv] According to the Idaho Food Bank and Idaho’s Map the Meal Gap report, released in July 2022, national food insecurity did not increase in 2020 largely due to a strong public and private response to the pandemic. The economic downturn resulting from the pandemic did highlight and exacerbate disparities among populations who experience food insecurity. In Idaho, 17 percent of the Hispanic and Latino population faced food insecurity in 2020 compared to 8 percent of the white, non-Hispanic population.[iv] Among children enrolled in Idaho public schools during the 2021-2022 school year, 27.26 percent were eligible for free or reduced-price lunch, a reduction from the previous year when 36.11 percent were eligible.[v] Idaho’s most rural counties tend to experience higher rates of food insecurity and limited access to healthy foods.[iv] Shoshone County is estimated to have the highest food insecurity rate, with 15.7 percent overall, and 20.7 percent among children in the county. As a comparison, Jefferson County had the lowest food insecurity rate, at 6 percent. Food insecure households often rely on low cost, low nutrient foods resulting in a greater risk of obesity for this under-resourced population.[vi] Adults with obesity are at increased risk for many diseases and health conditions including type 2 diabetes, stroke, and heart disease. TRANSPORTATION AND ACCESS TO PHYSICAL ACTIVITY OPPORTUNITY Maintaining a robust transportation system with safe options for all people regardless of age, income or ability to drive improves health. Transportation connects people to employment, healthcare, food, recreation and all the other places people need to access to live full and healthy lives. Without reliable and safe transportation, people are less likely to receive preventative healthcare and less able to participate in health promoting activities like healthy eating and physical activity.[vii],[viii] While only 3.9 percent of Idaho households do not have access to vehicles, 23.7 percent of households only have access to one vehicle, thereby increasing their reliance on alternative modes of transportation.[ix] Many Idahoans also face difficulties paying maintenance costs for the vehicles that they own, and others drive less as they age. Although rural areas have different needs than urban areas, an equitable and health promoting transportation system that works for all Idahoans would include safe and ADA accessible walking routes, safe and connected bicycle infrastructure, street connectivity, public transportation or shuttle options and diverse land uses so people have the opportunity to live within walking distance to key destinations. In 2021, approximately 35 percent of Idaho adults making less than $15,000 per year reported no physical activity outside of work, compared to 11.8 percent of those who make $75,000 or more per year.[x] Neighborhood design may help to explain this discrepancy, as people who live in neighborhoods where it is safe and enjoyable to walk, or bike are more likely to participate in these activities. At a national level, the 2022 Dangerous by Design report by Smart Growth America, found that while lower-income neighborhoods (those with a median household income of $2,500-$43,000) make up 17 percent of the population, they account for more than 30 percent of all pedestrian deaths.[xi] Communities that invest in active transportation options like sidewalks, protected bike lanes and public transportation not only help to protect the environment, but they also increase transportation equity and improve health.[viii] HOUSING Housing costs started to decrease in 2022, although not at a rate commensurate with the rapid increases seen in recent years. Purchase prices for homes in the state increased 115.87% percent over the past 5 years (Period ended 2022 Q3).[xii] Statewide, the median rent reportedly decreased 5.39 percent from December 2021 to 2022, down from a 58.0 percent increase from 2020 to 2021.[xiii] While slowing, the recent increase in the cost of housing without a comparable increase in income has resulted in many households struggling to meet living expenses. Many studies have shown that housing instability contributes to poor health and, as a result, increased healthcare costs. People who rent housing comprise 28.1 percent of Idaho’s occupied housing units, and of those who rent housing, 46.7 percent are cost burdened, meaning they pay 30 percent or more of household income toward their rent. For homeowners with a mortgage, 25.8 percent are cost burdened.[ix] According to the National Low Income Housing Coalition there is a shortage of 24,486 rental homes affordable to low-income households whose incomes are at or below 30% of the area median income in Idaho. Among these extremely low-income renter households, 66 percent are severely cost burdened meaning they spend more than 50 percent of their income on housing.[xiv] Housing cost burdened families are unable to afford other necessities and essential services, leading to poor downstream consequences, such as missed medical or dental check-ups. These decisions are often the determining factor turning acute health issues into costly chronic health conditions. The US Department of Housing and Urban Development (HUD) estimates that Fair Market Rent for a two-bedroom apartment in Idaho is $981.[xv] To afford this level of rent without paying more than 30 percent of income on housing, a household must earn $3,272 monthly or $18.87 per hour for a 40-hour work week. However, the average wage for those who rent their housing in Idaho is $16.10. People who make the minimum wage would need to work 104 hours per week to afford a two-bedroom rental home. Based on the estimates, certain areas of the state require much higher wages to afford a two-bedroom apartment, $21.50 per hour in Boise and $21.46 per hour in Blaine County.[xv] [i].

  • Access to Healthcare
    HEALTH PROFESSIONAL SHORTAGE In 2022, 100 percent of Idaho was a federally designated mental health professional shortage area, 98.7 percent of Idaho was a federally designated shortage area in primary care and 95.7 percent of Idaho was a federally designated dental health professional shortage area.[i] Primary care and dental health shortages areas increased in Idaho from 2021 to 2022. In 2022, the Idaho Hospital Association reported 51 hospital members throughout the state. Twenty-seven of these hospitals are critical access hospitals, located in Idaho. These small, rural hospitals also own primary and specialty care clinics and may be co-located with the hospital or operate as remote clinics.[ii] Prior to 2018, there were no medical schools (either allopathic or osteopathic) in the state. In 2018, the first college of osteopathic medicine began operating in Idaho for the purpose of training and developing physicians. The Idaho College of Osteopathic Medicine (ICOM) is a private, for-profit school which received pre-accreditation status while it continues working towards establishing full accreditation status from the Commission on Osteopathic College Accreditation. ICOM’s mission is to train competent and caring physicians prepared to serve persons in Idaho, Montana, North and South Dakota, Wyoming, and beyond with an emphasis on rural, underserved areas within this five-state region. IDAHO MEDICAID In SFY 2022, on average 414,7330 Idahoans were enrolled in Medicaid, a 48 percent increase from SFY 2019 average enrollment. The growth is due to the Medicaid expansion program.[iii] Medicaid serves individuals from birth to end of life, provided they meet eligibility criteria. In SFY 2022, 43.8% of Medicaid enrollees were children from birth to 18 years of age, another 6.6% are comprised of children with developmental disabilities up to age 21.29 Medicaid enrollment typically fluctuates depending on the state’s economy: When the economy is strong, more people are working and have access to healthcare coverage through their employers; however, when the economy is not performing well, more Idahoans seek healthcare assistance through Medicaid. In November 2018, voters passed a ballot proposition to expand Medicaid in Idaho. The goal of Medicaid expansion is to provide Medicaid coverage to individuals with incomes up to 138 percent of the Federal Poverty Level. “Prior to 2020, there were an estimated 78,000 Idaho residents in the coverage gap – ineligible for subsidies in the exchange and also ineligible for Medicaid.”[iv] The state implemented Medicaid expansion January 1, 2020. Estimates prior to the COVID-19 pandemic expected that an additional 91,000 people would be covered. As of January 2023, around 145,000 Idaho residents were enrolled in Medicaid expansion. These are individuals who have a monthly income of $1,563 or less, or are a family of four with a monthly income of $3,192 or less. Idaho hospitals report spending $42 million less on charity care and had $61 million less bad debt since Medicaid was expanded from 2019-2021.[v] IDAHO KIDS HEALTH COVERAGE According to a 2021 Idaho Kids Covered report, a project of Idaho Voices for Children, “Idaho had the highest increase in the rate of uninsured children in the entire country between 2017 and 2018.” The report emphasizes the critical importance of prioritizing health coverage for children, as they are “more likely to do better in school and grow up healthy.” As of 2021, 5 percent of children in Idaho are uninsured. This equates to 24,000 kids who do not have health coverage. The report also illustrates disparities that exist across income, age and geography, confirming that a child’s zip code impacts their health and access to care. Hispanic children are more likely than White children to be without coverage.[vi] Half of Idaho’s children (51 percent) are covered by their families’ employer-sponsored health insurance, while 35 percent are covered by Medicaid/CHIP, another 8 percent are covered through health insurance exchange, and 5 percent are uninsured.

PUBLIC HEALTH DISTRICTS

 

To facilitate the availability of public health services in communities, the state aggregated neighboring counties into seven local public health districts. The boundaries that separate each of the seven areas include geographic barriers, transportation routes and population centers. Access to healthcare and other services continued to be barriers to improving health outcomes for Idaho residents; however, Idaho's seven local public health districts represent the primary outlets for public health services. Each district is governed by a local board and responds to local needs to provide services that may vary from district-to-district, ranging from community health nursing and home health nursing to environmental health, dental hygiene, maternal and child health, immunizations and nutrition. Many services that the districts provide are through contracts with the division.
