Why is it important to use rates for comparison of health and disease among subpopulations?
subpopulations have different diets, culture, habits, genes and all these generate different risk factors for health and disease. Coal miners in West Virgina are substantially different in those things listed above as compared to Indians in Oregon.

It is important to use rates for comparison of health and disease among subpopulations because rates allow us to account for differences in population size and composition. When we compare health and disease outcomes among different subpopulations, such as different age groups or geographical regions, the rates provide a standardized measure that accounts for variations in the underlying population at risk.
Rates are typically expressed as the number of health events (e.g., cases of a particular disease) divided by the total population at risk, multiplied by a specific time period. By using rates, we can compare subpopulations with varying population sizes, which helps in identifying disparities and understanding the burden of disease more accurately.
Furthermore, rates allow us to adjust for differences in population characteristics, which helps in making valid comparisons. For example, if we want to compare the prevalence of a disease between two age groups, we need to consider that the age distributions might be different. By calculating rates within each age group, we can account for these differences and obtain a more meaningful comparison.
Overall, using rates for comparison of health and disease among subpopulations provides a standardized and equitable way to evaluate and understand the variations and disparities in health outcomes.
