Quick concept primer
A health disparity is a difference in health outcomes between groups, such as higher infant mortality or asthma rates in one population. A healthcare disparity is narrower: a difference in access to care or in the quality of care received, for example unequal treatment of patients with the same diagnosis and insurance. Social determinants of health are the conditions where people are born, live, learn and work, such as income, education, housing, neighborhood safety and food access. They differ from biological determinants like inherited gene variants.
Spatial inequality means resources and hazards are unevenly spread across places. Residential segregation, often produced by institutional practices like redlining, concentrates poverty and pollution in some neighborhoods. Environmental justice is the movement and principle that all groups deserve equal protection from environmental hazards and a real voice in siting decisions. Intersectionality holds that overlapping identities, such as race and gender, combine to produce experiences that cannot be predicted by adding each one separately. The Social Inequality pack adds flashcards and longer question sets on these terms and the theories behind them, and you can try the free sampler first.
Traps: compare rates, not raw counts, when populations differ in size, and remember that a correlation between low income and illness can reflect causation in either direction.
9 practice questions
Question 1
In a hospital audit, patients with the same fracture type, the same pain score and the same insurance plan are compared. Patients from one racial group are prescribed pain medication less often than patients from another group. This finding is best described as:
- a healthcare disparity.
- a biological determinant of health.
- social drift.
- an environmental justice violation.
Show answer and explanation
Answer: A. a healthcare disparity.
The patients are matched on condition, pain and insurance, yet the treatment they receive differs by group, which is a difference in the quality of care itself: a healthcare disparity. Nothing here involves inherited biology, downward movement in class due to illness, or the siting of environmental hazards.
Question 2
A county health office reports emergency visits for asthma in one year.
| Neighborhood | Residents | Asthma emergency visits |
|---|---|---|
| Next to a freight highway | 12,000 | 84 |
| Two miles from the highway | 15,000 | 30 |
How many times higher is the visit rate in the neighborhood next to the highway?
- 2.8
- 0.29
- 3.5
- 4.2
Show answer and explanation
Answer: C. 3.5
The rates are 84 / 12,000 = 70 per 10,000 and 30 / 15,000 = 20 per 10,000, so the rate ratio is 70 / 20 = 3.5. Choice A, 2.8, divides raw counts and ignores that the two neighborhoods have different populations. Choice B inverts the comparison.
Question 3
A city plans to build a waste transfer station in a low-income neighborhood where most residents belong to racial minority groups. Residents organize hearings, demand air monitoring and argue that their area already hosts more polluting sites than wealthier districts. Their campaign is best described as part of:
- gentrification.
- cultural relativism.
- urban renewal.
- the environmental justice movement.
Show answer and explanation
Answer: D. the environmental justice movement.
Environmental justice seeks fair distribution of environmental hazards across groups and a meaningful voice for affected communities in siting decisions, which is exactly what the residents demand. Gentrification is the influx of wealthier residents that displaces poorer ones, urban renewal is redevelopment of declining areas, and cultural relativism concerns judging cultures by their own standards.
Question 4
A historian finds a 1930s lending map that marked certain neighborhoods as high risk based on the race of their residents, so banks refused mortgages there. Decades later, those same neighborhoods have lower property values and fewer parks than nearby areas. This pattern most directly illustrates:
- individual discrimination by a single prejudiced person.
- spatial inequality produced by institutional practices.
- intergenerational upward mobility.
- relative deprivation theory.
Show answer and explanation
Answer: B. spatial inequality produced by institutional practices.
The lending map was an institutional policy that shaped where investment flowed, and its effects persist as an unequal distribution of resources across places, which is spatial inequality created by institutional discrimination (redlining). It is not the act of one prejudiced individual, it shows lasting disadvantage rather than mobility, and relative deprivation concerns perceived unfairness that motivates social movements.
Question 5
Each of the following is a social determinant of health EXCEPT:
- stable, affordable housing.
- years of formal education.
- an inherited variant in a gene that encodes a clotting factor.
- distance to the nearest grocery store selling fresh produce.
Show answer and explanation
Answer: C. an inherited variant in a gene that encodes a clotting factor.
An inherited gene variant is a biological determinant of health, set at conception rather than by social conditions. Housing, education and neighborhood food access are all conditions of where people live, learn and work, so they are classic social determinants of health.
Question 6
A sociologist finds that women of one racial group face a pay gap larger than what would be predicted by adding the separate average gaps for being a woman and for belonging to that racial group. Which concept best explains why the gaps do not simply add?
- Social reproduction
- Stereotype threat
- Double consciousness
- Intersectionality
Show answer and explanation
Answer: D. Intersectionality
Intersectionality argues that overlapping social identities interact, so the disadvantage of holding two marginalized identities can differ from the sum of each one alone. Social reproduction concerns passing class position across generations, stereotype threat concerns test performance under fear of confirming a stereotype, and double consciousness describes seeing oneself through the eyes of a dominant group.
Question 7
A state reports infant deaths in two groups during one year.
| Group | Live births | Infant deaths |
|---|---|---|
| Group X | 2,400 | 18 |
| Group Y | 3,000 | 9 |
What is the absolute difference in infant mortality rate between the two groups?
- 2.5 per 1,000 live births
- 4.5 per 1,000 live births
- 9 per 1,000 live births
- 6.0 per 1,000 live births
Show answer and explanation
Answer: B. 4.5 per 1,000 live births
Group X has 18 / 2,400 = 7.5 deaths per 1,000 births and Group Y has 9 / 3,000 = 3.0 per 1,000, so the absolute difference is 7.5 minus 3.0 = 4.5 per 1,000. Choice A is the rate ratio (2.5), not a difference, and choice C subtracts raw death counts without converting to rates.
Question 8
A long-term study follows adults who develop a severe mental illness. After diagnosis, many lose their jobs and move into lower-income neighborhoods, so the illness appears concentrated among people of low socioeconomic status. This explanation of the link between low status and illness is called:
- health selection, or social drift.
- social causation.
- intersectionality.
- environmental racism.
Show answer and explanation
Answer: A. health selection, or social drift.
In the drift or health selection explanation, illness comes first and causes downward movement in status. Social causation reverses the arrow, claiming that the stresses and hazards of low status cause illness. Intersectionality and environmental racism do not describe the direction between illness and status.
Question 9
A clinic serves many patients who speak little English. Which intervention most directly targets a healthcare disparity rather than a broader social determinant of health?
- Building a park near the neighborhood
- Raising the local minimum wage
- Lowering truck traffic on nearby roads
- Providing trained medical interpreters during visits
Show answer and explanation
Answer: D. Providing trained medical interpreters during visits
Interpreters change the access and quality of care delivered inside the clinic, which is the defining feature of a healthcare disparity. Parks, wages and traffic pollution shape health through living conditions outside the medical system, so they target social and environmental determinants rather than care itself.
