   2 Annual wages have been calculated by multiplying the hourly mean wage by a "year-round, full-time" hours
figure of 2,080 hours; for those occupations where  an hourly mean wage is not published, the annual wage has
been directly calculated from the reported survey data.

   3 Occupations listed will not sum to all-occupations total because the total includes occupations for which
data are not shown.

   NOTE: Data represent occupational employment and wages for establishments that received all of their
revenue from green goods and services. Establishments that did not generate revenue, such as government
establishments, nonprofits, or startups without positive revenue, reported all of their employment associated
with the production of green goods or provision of green services.
