Estimated Characteristics and Employment of Essential Workers in California, from May 2020 to June 2021

This fact sheet estimates the characteristics and employment numbers of workers in essential industries in California over the period from May 2020 to June 2021. Accurate estimates of essential workers in California are hard to produce for a number of reasons, including significant lags in data collection and reporting, and the instability of the labor market during the last 18 months. We therefore use multiple data sources to produce a range of estimates of the number of workers in California from May 2020 to June 2021 who meet the following three conditions: (1) working in essential industries, (2) not working from home, and (3) working for at least 1,000 hours cumulatively. We refer to workers meeting these three characteristics as active on-site essential workers.

Our method of producing these estimates is as follows. First, we use two worker surveys, the Current Population Survey (CPS) and the American Community Survey (ACS), to identify the proportion of workers in California meeting the above three conditions, by industry. We then apply those proportions to industry employment counts between May 2020 and June 2021, using Current Employment Statistics (CES) data. We then produce a range of final employment estimates.

Table 1 shows estimated characteristics for each industry: the proportion that were essential workers (column 1), the proportion not working from home (column 2), and the proportion working at least 1,000 hours (column 3). We estimate the proportion of essential workers with the monthly CPS, using California’s list of “Essential Critical Infrastructure Workers.”[1] We also use the CPS to identify the percent of workers who were working on-site — that is, they were not working from home. We estimate the proportion of workers who worked at least 1,000 hours for all workers using 2019 ACS data. See Appendix for details on these three measures.

Table 2 shows the resulting employment estimates for active on-site essential workers in each industry. We arrive at these estimates by applying the proportions in Table 1 to the employment counts from the CES. We provide high, medium, and low estimates, given the extreme variability in employment during the past 13 months (May 2020 through June 2021). The “high” estimate uses the highest monthly employment count from the CES for each industry during this time span. The “low” estimate uses the lowest monthly count, and the “medium” estimate uses the average monthly employment across the 13 months.

Appendix

We identify essential workers in the IPUMS – Current Population Survey basic monthly datasets following California’s list of “Essential Critical Infrastructure Workers.” We include all occupations in the essential industries. We also use the Current Population Survey (CPS) to identify workers not working from home; the CPS began asking respondents in May 2020 if the worker works remotely due to the pandemic. We then estimate the proportion of workers who are in essential industries and also not working from home over the period May 2020 to June 2021.[2]

We estimate annual number of hours worked using the IPUMS – American Community Survey one-year sample for 2019 (ACS), and use this calculation to estimate the proportion of all workers working at least 1,000 hours across industries.

In analyzing the CPS and the ACS, we restrict our analysis to workers who are 18-64 year-olds, with non-zero working hours in the last week or non-zero earnings in the past year, who were not self-employed or unpaid family workers, and who were at work last week, or had a job but were not at work last week.

Our employment counts come from the Current Employment Statistics (CES), which provides detailed industry estimates of employment of nonfarm workers in California. We append the CES data with total farm sector employment estimates from California’s Employment Development Department, and use this information to calculate high, medium, and low employment in each industry over the period May 2020 to June 2021.

To obtain our estimated employment counts of active on-site essential workers in California, we build a crosswalk to match the CPS/ACS industries with the CES industries. We multiply the high, medium, and low employment in each industry by two estimated proportions: 1) proportion of workers who are in essential industries and also not working from home, and 2) proportion of workers working at least 1000 hours.[3]

Endnotes

[1] Also see Thomason & Bernhardt (2020).

[2] For readers’ reference, in Table 1, we list the proportion of workers in essential industries and the proportion of workers not working from home separately.

[3] By multiplying our employment counts and the combined proportion of onsite essential workers by the proportion of workers working at least 1,000 hours, which comes from the 2019 ACS, we are assuming that this proportion remains the same in the period of interest, and that this proportion is not related to essential industry status or not working from home status.
