Rate adjustment epidemiology
The process of age-adjustment by the direct method changes the amount that each age group contributes to the overall rate in each community, so that the overall age-adjusted death rates are calculated and discusses Age-adjusted death rate = total expected deaths X 1,000 Modern Epidemiology (Chapter 5).

The following example illustrates how these varying frequencies can affect a summary measure. Table 1 indicates that in 1970, 5,022 out of the 562,887 white women in Miami died, and that 285 of the 106,917 white Alaskan women died. The respective overall (crude) death rates are 8.92 per 1,000 and 2.67 per 1,000. rate [rāt] the speed or frequency with which an event or circumstance occurs per unit of time, population, or other standard of comparison. adjusted rate a fictitious summary rate statistically adjusted to remove the effect of a variable, such as age or sex, to permit unbiased comparison between groups having different compositions with respect to An age-adjusted rate is a measure that controls for the effects of age differences on health event rates. When comparing across geographic areas, some method of age-adjusting is typically used to control for the influence that different population age distributions might have on health event rates. 3.4Rate Adjustment (“Standardization”) For uniformity of language, the term rate will be used to refer to any incidence or prevalence measure. Direct Standardization The directly adjusted rate (aR direct) is a weighted average of strata-specific rates with weights derived from a reference population: aR direct = ∑w i r i where =∑ i i i N N w N Task 1: Calculate Age-Standardized Estimates. This task addresses how to generate age-adjusted prevalence estimates and means. Task 2: Calculate Population Counts. This task addresses how to calculate the number (i.e. the count) of people with a certain condition or disease in the non-institutionalized U.S. population. Age-Adjusted Rates Age adjusting rates is a way to make fairer comparisons between groups with different age distributions. For example, a county having a higher percentage of elderly people may have a higher rate of death or hospitalization than a county with a younger population, merely because the elderly are more likely to die or be
