Healthy People 2030 organizes the social determinants of health into 5 domains:

  1. Economic Stability
  2. Education Access and Quality
  3. Health Care Access and Quality
  4. Neighborhood and Built Environment
  5. Social and Community Context

Housing Instability is a key issue in the Economic Stability domain. 

Housing instability has no standard definition.1,2 It encompasses a number of challenges, such as having trouble paying rent, overcrowding, moving frequently, staying with relatives, or spending the bulk of household income on housing.12 These experiences may negatively affect physical health and make it harder to access health care.134 This summary will discuss the cost of housing as well as the health effects of substandard housing and forced evictions. Certain populations may be more affected by housing instability, such as children who move frequently and people who have spent time in prison.

Households are considered to be cost burdened if they spend more than 30% of their income on housing and severely cost burdened if they spend more than 50% of their income on housing.5 Cost-burdened households have little left over each month to spend on other necessities such as food, clothing, utilities, and health care.16 Black and Hispanic households are almost twice as likely as white households to be cost burdened.7

In 2014:8

  • 21.3 million households were cost burdened—of these, 11.4 million households were severely cost burdened.
  • 83% of households earning less than $15,000 a year were cost burdened.

Due to a limited rental market with few affordable vacancies, people with the lowest incomes may be forced to rent substandard housing that exposes them to health and safety risks such as vermin, mold, water leaks, and inadequate heating or cooling systems.68 They may also be forced to move in with others, potentially resulting in overcrowding.9 Overcrowding is defined as more than 2 people living in the same bedroom or multiple families living in 1 residence.310 Overcrowding may affect mental health, stress levels, relationships, and sleep, and it may increase the risk of infectious disease.111213

Housing costs that are more than a household can reasonably afford can lead to foreclosure or eviction (a forced move).9 Forced moves may also happen if a landlord is in foreclosure or the property is deemed unsafe for living.14 Foreclosures cause loss of money and possessions and can damage the social fabric of neighborhoods.15 Evictions that go through the court system result in a permanent record, which can cause potential landlords to refuse to rent to evictees in the future.16 Research has shown that renters who are forced to move are more likely to relocate to poorer and higher-crime neighborhoods compared to those who move voluntarily.17 Evictions may be especially traumatizing to residents due to short relocation notices.1718 Suicide rates linked to stress doubled between 2005 and 2010,19 when the U.S. experienced historically high rates of foreclosures, including foreclosures on rental properties.820

Housing instability may impact some populations more than others. Moving 3 or more times in 1 year, often called “multiple moves,” has been associated with negative health outcomes in children.321 Children who move frequently are more likely to have chronic conditions and poor physical health.21 They may also be less likely to have consistent health insurance coverage.21

People who have spent time in prison may be discriminated against by potential landlords, lose eligibility for public housing, and struggle to maintain stable housing.2223 People are often released from prison with minimal income, and those who find employment face reduced earnings and may have difficulty paying for housing.2223 One study found that 5 years after release, black individuals who have spent time in prison were more likely to experience housing instability than white individuals who have spent time in prison, even after controlling for earnings.23

Homelessness is housing deprivation in its most severe form.9 Homelessness is defined as “lacking a regular nighttime residence or having a primary nighttime residence that is a temporary shelter or other place not designed for sleeping.”24 About 565,000 people were homeless in the U.S. in 2015.8 A study of newly homeless people in the New York City shelter system found that 6% had diabetes, 17% had hypertension, 17% had asthma, 35% had major depression, and 53% had a substance use disorder—indicating that chronic disease is more common among people who are newly homeless than among the general population.25 People who are homeless also have an increased risk of premature death.26 A study in Boston found that for 25- to 44-year-olds, the mortality rate was 9 times higher for men who are homeless and 10 times higher for women who are homeless compared to the general population of Massachusetts—and the mortality rate for 45- to 65-year-olds was 5 times higher for people who are homeless.26 The health effects of homelessness can begin early in life, as pregnant women who are homeless are more likely to deliver preterm and low birthweight babies.27

In addition to the direct health effects of housing instability, frequent moves may prevent individuals and families from building long-lasting attachments to neighborhoods. Neighborhood characteristics can strongly influence health. For example, people living in lower-income areas rate their own health lower than those living in higher-income neighborhoods.28 The Moving to Opportunity (MTO) program provided very low-income families with rental assistance and housing counseling to move from high-poverty to low-poverty neighborhoods.2930 Research on the effects of the MTO program showed that people who moved from high-poverty to low-poverty neighborhoods before the age of 13 were more likely to attend college, had higher incomes, were less likely to be single parents, and lived in better neighborhoods as adults.31 Adult women given vouchers through MTO had a lower prevalence of extreme obesity and diabetes after 10 to 16 years compared to those not given vouchers.32

Housing subsidies administered by the federal government provide financial assistance to help low-income people pay rent.63334 However, households may be on waitlists for several years before receiving assistance.61833 Due to limited funds and the large number of households in need, only 26% of eligible households received federal housing subsidies in 2013.8 Further work is needed to explore potential strategies to reduce housing instability. More research is also needed to identify how to reduce the negative effects of housing instability on health outcomes and health disparities. This additional evidence will facilitate public health efforts to address housing instability as a social determinant of health.
