Nearly 145,000 seniors age 65 and older live in St. Louis County. They are among the fastest growing segment of our population. Understanding key demographic, economic, social and health indicators about seniors is helpful for sustaining the community engagement of seniors and for planning services. This web application seeks to increase the accessibility of such information for St. Louis County and for 37 Census Tract Neighborhood Areas within the county. Each subject heading to the left includes a description of trends related to seniors with supporting tables, maps and graphics. Other features such as population pyramids, area profiles and data queries are accessible above and described in the Application Summaries.
