Question: The U S Department of Commerce tracks the number of workers

The U.S. Department of Commerce tracks the number of workers employed in various industries in the United States. It summarizes these data in the Statistical Abstract of the United States. This regularly appearing volume contains a rich collection of tables and charts that describe the country.
The data shown in the following table appear in Table 620 in the 2012 edition, available online at This table summarizes a categorical variable from each of two data tables. These categorical variables identify the type of industry that employs the worker. Each row in the underlying data tables represents an employee, either in 2000 or 2010.
Each value shown in this frequency table is a rounded count given in thousands. For example, about 2,464,000 were employed in agriculture and related industries in 2000.
