The Community Assessment Survey for Older Adults (CASOA) was sent to a scientifically random sample of adults ages 50 and older in early 2022. Additional input from the community was collected at more than a dozen community forums and focus groups.
The survey was available in Arabic, English, Korean, Spanish and Vietnamese. The community survey asked for information about the lifestyles of older adults, including opportunities to work, socialize and volunteer, as well as issues they face, such as retirement, housing and caregiving, and their use of community services like public transportation and senior centers.
The Community Assessment Survey for Older Adults (CASOA) was developed and administered for Fairfax County by the National Research Center at Polco (NRC). The CASOA™ survey instrument (and the way it is administered) are standardized to ensure high quality survey methods and to make sure the results are comparable across CASOA communities.
In March 2022, 22,000 surveys were mailed to a random sample of households with a high likelihood of containing someone over 50. The sample size was chosen so that the results would have a 95% confidence interval and be accurate within +/-2 percentage points. 2,919 surveys were returned for a 13% response rate.
Weighting was applied to the results to ensure that the survey data is representative of the population of Fairfax County. The characteristics used for weighting were age, sex, race, ethnicity, and housing type (rent or own home). See tables below for additional data.
