The relative rate in this chart represents the ratio of the rate of respiratory disease hospitalizations in the lowest income quintile (lowest 20%) to the rate of respiratory disease hospitalizations in the highest income quintile. Ratios greater than 1 indicate greater risk of respiratory disease hospitalization for those in the lowest income quintile, with higher values representing increased risk for the lower income group.

The population attributable fraction in this chart shows the percent reduction in the rate of respiratory disease hospitalizations if each socioeconomic group experienced the hospitalization rate of the top income quintile (top 20% on income).
