As with most chronic diseases, increased age is a well-known and powerful risk factor for the development of CKD (National Kidney Foundation,
http://www.kidney.org/kidneydisease/ckd/index.cfm); consequently, prevalence of CKD is highest among older Americans (Coresh et al., 2007). Additionally, U.S. incidence of ESRD is highest among older adults (United States Renal Data System, 2011). Although age is not modifiable, it remains important for a U.S. CKD surveillance system to estimate the proportions of the population who will be among the older age (i.e., higher-risk) groups for both incidence and progress, as the U.S. population changes over time. The U.S. Census Bureau (www.census.gov) conducts a decennial population census, as mandated by the U.S. Constitution to guide apportionment of seats in the U.S. House of Representatives. Census 2000 and Census 2010 contained items regarding age, gender, race, Hispanic/Latino origin, and housing characteristics and was administered to the entire resident population of the United States. From the data collected, both population estimates (www.factfinder2.com) and projections (United States Census Bureau, 2008;
http://www.census.gov/population/www/projections/index.html) are available publicly.
