Our recently published paper “The Public Cost of Low-Wage Jobs in the United States Construction Industry” explored the use of five safety net programs by construction workers and their families. Though construction used to provide well-paying jobs to workers without a college education, job quality has deteriorated to the point that many construction workers earn wages too low to make ends meet and therefore turn to the public safety net to make up the difference. We found that nationwide, 39% of families of construction workers are enrolled in one or more safety net program at a cost of almost $28 billion per year, and three times as many construction workers as all workers lack health insurance (31% compared to 10%).[1]

Throughout the country, construction is a highly competitive industry in which projects are frequently awarded on the sole basis of the lowest bid.[2] One of the most effective ways to minimize costs and win contracts is to “reduce labor costs through whatever means possible.”[3] The primary strategies to this end are paying low wages without benefits, misclassifying employees as independent contractors, and paying workers under the table. Overall, between 12.4 and 20.5% of construction workers are either misclassified or paid under the table.[4] These practices drive a “race to the bottom” in the industry, which degrades job quality and leaves many workers unable to support themselves and their families. [5]

In this research brief we provide estimates of safety net use among families of construction workers in Illinois. We find that 34% of families of construction workers in Illinois are enrolled in one or more safety net programs at a cost to the state and the federal government of over half a billion dollars per year. By comparison, among all Illinois workers, 30% have a family member enrolled in one or more safety net programs. The rate at which construction workers lack health insurance (21%) is more than two and a half times the rate for all workers in Illinois (8%).

About Illinois’s Construction Industry

  • In Illinois there are approximately 312,000 people employed in construction, about 1 in 20 workers statewide.[6]
  • Just prior to the COVID-19 pandemic, in 2019, construction contributed $30 billion, or 3.4%, of Illinois’s GDP.[7]
  • Construction accounted for $25.9 billion in personal income, or $1 out of every $29 in total state earnings in 2019.[8]
  • In Illinois, 34.4% of workers in the construction industry are covered by collective bargaining agreements, two and a half times the national rate of 13.6%.[9]

Data and Definitions

We examine Illinois construction workers’ and their families’ utilization of the five largest means-tested safety net programs for which data are available: Medicaid; Children’s Health Insurance Program (CHIP); basic household income assistance under Temporary Aid for Needy Families (TANF); Earned Income Tax Credit (EITC); and Supplemental Nutrition Assistance Program (SNAP). Responsibility for funding the health programs is shared by Illinois and the federal government. We include only the cash assistance portion of TANF, and this program too receives funding from both Illinois and the federal government. While there is a state-level EITC program, in this analysis we include only the federal EITC. The federal government alone funds SNAP. We analyze only programs that function as income supplements, omitting job-training, housing cost assistance, educational, and other programs that indirectly assist low-income families.

To calculate the numbers of working families who participated in safety net programs, we restrict the sample to those who work 27 or more weeks per year and 10 or more hours per week in all industries in Illinois. We exclude workers who live in institutional group quarters. To identify construction workers, we further use the 1990 Census Bureau industrial code All Construction (60), and the 2010 Census Bureau occupation codes from First-Line Supervisors of Construction Trades and Extraction Workers (6200) to Construction Workers, n.e.c. (6765), and we include W2 workers and the not-incorporated self-employed but exclude the incorporated self-employed.


Table 1 shows the annual enrollment in safety net programs of construction workers and their families in Illinois between 2015 and 2019. We estimate that 34% of construction working families are enrolled in at least one program, more than the 30% of all working families. Construction working families have higher enrollment than all working families in every program except TANF, which has negligible enrollment among both groups in Illinois.

Overall, construction working families are around 13% more likely than all working families to participate in one or more means-tested safety net programs in Illinois. These families are almost one and a half times as likely to be enrolled in Children’s Medicaid and 20% more likely to be enrolled in EITC.

Table 2 presents the combined annual expenditures by the State of Illinois and the federal government on safety net program usage by construction working families and all working families, again averaged over the years 2015-2019. In total, over half a billion dollars ($518 million) is spent on safety net program utilization annually by construction working families in Illinois.

Table 3 presents the health insurance coverage status of construction workers and all workers in Illinois. The rate at which construction workers lack health insurance (21%) is more than two and a half times the rate for all workers in Illinois (8%).

Determining the full cost of uninsurance in Illinois, let alone the cost for uninsured construction workers, is beyond our scope. But in addition to causing hardship for uninsured construction workers, uninsurance creates significant expenses for states, counties, and the federal government. The Kaiser Family Foundation reports that in the years 2015-2017, uncompensated health care costs for the uninsured nationwide averaged $42.4 billion per year, with the public picking up around 80% of these costs.[10]


The low wages and exploitative practices in the construction industry, both in Illinois and nationally, cause profound hardship for workers and their families. It also costs the public. When employers misclassify their workers or pay them under the table, they are defunding and defrauding government programs, including workers’ compensation, Social Security, and Medicare. A study published in early 2021 found that 20% of the construction workforce in Illinois is misclassified or paid off the books. As a result, the state loses $186 million a year in tax revenue. These workers earn 29% less than legally employed construction workers.[11] Low-road employment practices like this cause the above-average utilization of safety net programs by construction working families in Illinois, as found in this analysis. Importantly, the numbers provided in this analysis do not fully reflect the deprivation among this workforce. Undocumented immigrants currently comprise 13% of the construction workforce nationwide (compared to 5% of the overall US workforce),[12] and with rare exceptions they are ineligible for state and federal assistance.[13] Their working conditions, among the worst in the industry, are not reflected in this analysis.

In most states, general contractors and subcontractors are not liable for—and in fact benefit from—payroll fraud found further “down the chain” of subcontractors; these practices continue “with or without the knowledge, assistance or willful ignorance of the owners, developers, general contractors, or construction managers.”[14] In the absence of legislation preventing these practices, construction workers in Illinois should expect to continue to be exploited and cheated, and lawful contractors should expect to find it more and more difficult to compete in the industry.

Appendix: Methods

We mainly rely on four sources of data: the US Census Bureau’s American Community Survey (ACS), the March Supplement of the US Bureau of Labor Statistics Current Population Survey (CPS), the US Bureau of Labor Statistics Occupational Employment Statistics (OES), and administrative data from the Medicaid, CHIP, TANF, EITC, and SNAP programs. Medicaid figures exclude aged, blind, and disabled enrollees. The ACS surveys a large number of respondents and asks them about their work history, income, and family structure. The March Supplement of CPS, also known as the Annual Demographic Supplement, asks respondents about receipts of cash and noncash transfer payments during the past year and includes questions about the programs we examine in this analysis.

Survey databases like the ACS and CPS frequently have safety net program utilization counts that differ from program administrative data. We adjusted the CPS so that its program utilization estimates match the program administrative data. The CPS does not provide a large enough sample size to accurately estimate program utilization for construction workers at the state or county levels. The ACS does have sufficient sample size for this analysis but lacks specific questions about program utilization, and its occupational employment counts differ from more accurate data like the OES. On the other hand, while the OES has accurate employment counts for wage workers, it does not include independent contractors. To overcome these issues, we built a model using CPS data to predict program utilization based on income, demographics, and family structure. We then used that model to impute program utilization onto the ACS data. We calculated the ratio of wage workers to non-incorporated self-employed workers based on the ACS and used it to adjust the OES data for non-incorporated self-employed workers, and then adjusted the employment counts in the ACS to match the adjusted OES data. Finally, we used that imputed and adjusted ACS data to analyze safety net program utilization in families of construction workers.
