Employment fell in the 13 largest counties in Illinois from December 2019 to December 2020, the U.S. Bureau of Labor Statistics reported today. (Large counties are those with annual average employment levels of 75,000 or more in 2019.) Regional Commissioner Jason Palmer noted that Cook County (-10.1 percent), Kane County (-9.1 percent), and Winnebago County (-9.0 percent) had the largest over-the-year decreases in employment. (See chart 1 and table 1.)

National employment decreased 6.1 percent over the year, with 352 of the 357 largest U.S. counties reporting declines. Maui + Kalawao, HI, had the largest over-the-year decrease in employment with a loss of 22.8 percent. Utah, UT, experienced the largest over-the-year percentage increase in employment with a gain of 3.8 percent.

Among the 13 largest counties in Illinois, employment was highest in Cook County (2,377,000) in December 2020. Within Cook County’s private industry, health care and social assistance accounted for the largest employment. Together, the 13 largest Illinois counties accounted for 80.4 percent of total employment within the state. Nationwide, the 357 largest counties made up 73.1 percent of total U.S. employment.

Employment and wage levels (but not over-the-year changes) are also available for the 89 counties in Illinois with employment below 75,000. Wage levels in 88 of the 89 smaller counties were below the national average in the fourth quarter of 2020. (See table 2.)

Large county wage changes

All 13 large Illinois counties reported average weekly wage gains from the fourth quarter of 2019 to the fourth quarter of 2020. (See chart 2.) Five counties had rates of wage gains that were above the national rate of 13.0 percent, with the largest gain in McLean County (+18.4 percent). Over-the-year wage gains among Illinois’ eight other large counties ranged from 12.9 percent to 7.5 percent.

Among the 357 largest counties in the United States, 356 had over-the-year wage increases. Nationally, across most industries, increases in average weekly wages reflect substantial employment declines combined with wage increases. The lowest paying industry, leisure and hospitality, had the largest employment loss, which results in higher average weekly wages for the industry and the nation. San Francisco, CA, had the largest percentage wage increase (+44.3 percent). Ector, TX, had the only over-the-year percentage decrease (-7.5 percent).

Large county average weekly wages

Average weekly wages in 3 of the 13 largest counties in Illinois were above the national average of $1,339 in the fourth quarter of 2020. Weekly wages in these three counties ranked among the top 75 nationwide: Lake ($1,637, 25^th), Cook ($1,571, 39^th), and DuPage ($1,456, 56^th).

Among the largest U.S. counties, 89 reported average weekly wages above the U.S. average in the fourth quarter of 2020. Santa Clara, CA, had the highest average weekly wage at $3,690. Average weekly wages were below the national average in the remaining 268 counties. At $760 a week, Cameron, TX, had the lowest average weekly wage.

Average weekly wages in Illinois’ smaller counties

Among the 89 smaller counties in Illinois—those with employment below 75,000—Rock Island ($1,561) reported an average weekly wage above the national average of $1,339. Pope County ($609) reported the lowest average weekly wage in the state.

When all 102 counties in Illinois were considered, 14 reported average weekly wages of less than $800, 35 registered wages from $800 to $899, 25 had wages from $900 to $999, and 28 had average weekly wages of $1,000 or higher. (See chart 3.)

Technical Note

Average weekly wage data by county are compiled under the Quarterly Census of Employment and Wages (QCEW) program, also known as the ES-202 program. The data are derived from summaries of employment and total pay of workers covered by state and federal unemployment insurance (UI) legislation and provided by State Workforce Agencies (SWAs). The average weekly wage values are calculated by dividing quarterly total wages by the average of the three monthly employment levels of those covered by UI programs. The result is then divided by 13, the number of weeks in a quarter. It is to be noted, therefore, that over-the-year wage changes for geographic areas may reflect shifts in the composition of employment by industry, occupation, and such other factors as hours of work. Thus, wages may vary among counties, metropolitan areas, or states for reasons other than changes in the average wage level. Data for all states, Metropolitan Statistical Areas (MSAs), counties, and the nation are available on the BLS web site at www.bls.gov/cew. However, data in QCEW press releases have been revised and may not match the data contained on the Bureau’s web site.

QCEW data are not designed as a time series. QCEW data are simply the sums of individual establishment records reflecting the number of establishments that exist in a county or industry at a point in time. Establishments can move in or out of a county or industry for a number of reasons–some reflecting economic events, others reflecting administrative changes.

The preliminary QCEW data presented in this release may differ from data released by the individual states as well as from the data presented on the BLS web site. These potential differences result from the states’ continuing receipt, review and editing of UI data over time. On the other hand, differences between data in this release and the data found on the BLS web site are the result of adjustments made to improve over-the-year comparisons. Specifically, these adjustments account for administrative (noneconomic) changes such as a correction to a previously reported location or industry classification. Adjusting for these administrative changes allows users to more accurately assess changes of an economic nature (such as a firm moving from one county to another or changing its primary economic activity) over a 12-month period. Currently, adjusted data are available only from BLS press releases.
