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 211.
6. With the filter in place, aggregate the “emp” column across all records.

Produced Goods

How to Download Your Data

Note: The Oil & Gas Snapshot uses the same production economic indicator value for the Processing and Production sub-sectors. This value is based on crude oil and gross withdrawals of natural gas, which are inputs to processed petroleum products and processed natural gas.

1. For petroleum quantity produced:
   1. Go to https://www.eia.gov/dnav/pet/pet_crd_crpdn_adc_mbbl_m.htm
   2. Change the displayed “Period-Unit” dropdown to “Annual-Thousand Barrels”
   3. Click “Download Series History.” The resulting spreadsheet file will contain a worksheet, “Data 1” with “U.S. Field Production of Crude Oil (Thousand Barrels)” as Column B.
   4. To convert petroleum (thousand barrels) to Btu, multiply each annual value by 5,800,000,000.
2. For natural gas quantity produced:
   1. Go to https://www.eia.gov/dnav/ng/ng_prod_sum_a_EPG0_FGW_mmcf_m.htm
   2. Confirm that the “Data Series” dropdown displays “Gross Withdrawals.”
   3. Change the displayed “Period-Unit” dropdown to “Annual-Million Cubic Feet”
   4. Click “Download Series History.” The resulting spreadsheet file will contain a worksheet, “Data 1” with “U.S. Natural Gas Gross Withdrawals (MMcf)” as Column B.
   5. To convert natural gas (MMcf) to Btu, multiply each value by 1,037,000,000.
3. Sum the converted petroleum values with the converted natural gas quantity values for each year to calculate the total quantity produced in Btu in each year.

Constant Dollar Output Value (2017)

How to Download Your Data

1. The constant dollar output metric uses inflation-adjusted economic output values. This contrasts with the dollar value of gross output (nominal output), which does not account for inflation.
2. The GDP Implicit Price Deflator (IPD) is used to adjust the dollar value of gross output for inflation.
3. The IPD is calculated by dividing nominal economic output (i.e., GDP) by constant dollar economic output and reflects the impact of prices on the measure of economic output. It is similar to the widely reported Consumer Price Index, but the IPD is more commonly used to reflect price increases facing businesses as well as consumers. The IPD is specified in the RCRA regulations.
4. The IPD is indexed to a base year. When this chart was created, the IPD used 2017 as the base year (2017 IDP = 100). For each annual economic output data element in the Sector Snapshot data, nominal output values are converted to constant dollar output values using this formula: Constant Dollar Output Value = Nominal Output Value (as currently displayed in Sector Snapshots) / [(IPD for current year) / (IPD for base year)]
5. IPD data is sourced from the Federal Reserve Bank of St. Louis (FRED) at https://fred.stlouisfed.org/series/GDPDEF#.
6. The constant dollar output values are also used to calculate intensity ratios for each environmental performance indicator.
