The study involved 6,596 people from Evans county and 3,921 people from Bulloch county. The study population from Evans county consisted of African-American and Caucasian males, ages 40-74, along with a 15-39 year old group that were involved in other studies. Then, the people were divided up into 10 random, equal in size, random samples. Also, a 50% random sample of the 15-39 year old group was taken by including people from the first five samples solely. By comprising this type of sampling, secular trends in disease patterns, along with possible aging of laboratory reagents were randomized.

The study was done in Evans County, Georgia. Evans County is located in the southeastern portion of the United States. It is situated on the coastal plain estimating around 60 miles inland from the seaport of Savannah, GA. Around half of the population lives on farms while the other half lives in meager little villages. An example is Claxton. Claxton is a town that has a population of 2,000. About 40 percent of the population are Negro. This ties in with the hypothesis that was declared; coronary heart disease seemed to occur less commonly among Negro than white patients. The white population of Evans County was large enough to provide an adequete number for the study, but the Negro population was considered too small. Therefore, a good amount of Negros from the Bulloch county was incorporated into this study.
