Which concept refers to the adjustment of rates to account for differences in population composition, with age being most commonly adjusted for?

• A. Administrative Law
• B. Adjusted Rates
• C. Age-adjusted Mortality Rate
• D. Access

Answer: (B)

When rates are adjusted to account for differences in a population’s makeup, the idea is to remove the influence of that structure so comparisons are fair. The general term for this practice is adjusted rates. Age is often the focus because it has a strong impact on many health outcomes, so most adjustments use age to standardize the rates across populations or over time. A common, specific example is the age-adjusted mortality rate, which computes mortality in each age group and then combines those figures using a standard age distribution to produce a single rate that isn’t biased by different age structures.

Other terms don’t fit as well: administrative law deals with rules governing government agencies, and access relates to the ability to obtain health services. Age-adjusted mortality rate is a specific application of the broader concept of adjusted rates.
