On Thursday, immigrants across the country went on strike to demonstrate their worth in the United States. In DC, immigrants make up 26 percent of the total workforce, and for some occupations the percentage is much higher.

That's according to an analysis of data from the Bureau of Labor Statistics (BLS) and the American Community Survey (ACS) by Ginger Moored of DC’s Office of Revenue Analysis.

A sizeable number of area restaurants closed during the “Day Without Immigrants,” along with childcare centers and schools. Many of the people who work in those industries are immigrants.

Other occupations with large numbers of immigrants include include carpenters (80%), taxi drivers and chauffeurs (70%), construction laborers (54%), and economists (46%).

It's especially interesting to see this list include economists given how DC's high concentration of this occupation is. According to this analysis and data from the BLS, one in six economists in the United States is an immigrant working in DC.

Immigrants tend to cluster in specific occupations, and specific occupations tend to be dominated by immigrants from specific places. This phenomenon seems to be at least partially the result of the support networks that exist where friends and relatives have gone before. Immigrant entrepreneurship also tends to be higher in such occupations.
