Employment

How to Download Your Data

Note: The data are available in a comma-delimited text format that must be imported into a software package that will allow you to analyze the file.

1. Go to https://www.census.gov/programs-surveys/cbp/data/datasets.html
2. Click on any link labeled “County Business Patterns: YEAR.” On the resulting page, click the “Complete U.S. File” link and download the corresponding file. Repeat this process for each year corresponding to years presented in the graphic.
3. Open each file in a software package of your choice that can process comma-delimited text files. Repeat the steps below for each file.
4. For entities with suppressed data, the Census Bureau replaces all employment values with zeroes and this underestimates the total number of employees in each sector. Using your software package, replace the suppression flags with the midpoint of the Data Suppression Flag employment ranges per the table below.

   Empflag Data Suppression Flag	Employment Size Class		Midpoint
   	Min	Max
   A	0	19	10
   B	20	99	60
   C	100	249	175
   E	250	499	375
   F	500	999	750
   G	1000	2,499	1,750
   H	2,500	4,999	3,750
   I	5000	9,999	7,500
   J	10,000	24,999	17,500
   K	25,000	49,999	37,500
   L	50,000	99,999	75,000
   M	100,000	>100,000	100,000

5. In your software package, filter the data for NAICS codes that begin with 2211.
6. With the filter in place, aggregate the “emp” column across all records.
