Snapshots of 100 Industries
Industries at a Glance, a site from the U.S. Bureau of Labor Statistics, contains snapshots of more than more than 100 industries, arranged alphabetically and by NAICS industry code. The site overview says, "These pages display a ‘snapshot’ of national data obtained from different BLS surveys and programs. Many programs also produce additional industry detail, including state and regional data."
The Accommodation industry (NAICS 721) snapshot, for example, includes data on employment, union membership, layoffs, employment by occupation, earnings, prices, establishments, and so on.
