Population trend data are essential for public health program planning and evaluation. Changes in population size and demographic composition alter service need and may confound health impacts. Nationally, over the past decade, the child population decreased by 1.4%, while the total U.S. population increased by 7.4%. In 2020, the 0-17 age group accounted for 22.1% of the U.S. population and was more multi-racial than in 2010. Consistent with national trends, the child and young adult population in San Francisco is trending smaller and more diverse. Unlike national data, local data suggest a faster rate of decrease (-5%) for the 0-24 age group, and a child population share that is only about half the size of the child population nationwide.
