Social and Human Service Assistants pay in District of Columbia and Missouri
The May 2025 BLS OEWS median for Social and Human Service Assistants is $59,460 per year in District of Columbia. It is $41,780 per year in Missouri. District of Columbia is 42.3% above Missouri on the published median.
Both rows use SOC 21-1093 and the same annual wage metric. Median means the middle of each area's published wage spread. It is not one worker's pay. The larger median is not proof that one place gives a better job or a better result. It is one wage fact from one source period.
BLS lists 2,080 wage and salary jobs in District of Columbia and 6,200 in Missouri. Those are survey job counts, not open posts. Read pay, job scale, local share, and price level as separate facts before you make a choice.
