51821

Analysis

NAICS 51821 is the 2022 NAICS industry for computing infrastructure providers, data processing, web hosting, and related services, part of 5182 (Computing Infrastructure Providers, Data Processing, Web Hosting, and Related Services).

It has only one more detailed code, 518210, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 18,544 US establishments in this code in 2023, employing 629,527 people at an average annual payroll of $147,665 per employee (96th percentile of national industries). 56% of the establishments have fewer than five employees, which is close to the national mix.

Between 2018 and 2023 the number of establishments grew 6% and employment rose 15%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
