What are Adverse Effect Wage Rates?

Learn how the AEWRs are calculated and better understand how these minimum wage rates are determined.

Local industry sources have voiced concern about issues with the H-2A visa program, and many do not know how the minimum wage rates paid to H-2A workers, called the Adverse Effect Wage Rates (AEWRs), are calculated. In this article, we provide information about how the AEWRs are calculated and additional insights to help local agricultural stakeholders better understand how these minimum wage rates are determined.

The United States Department of Agriculture (USDA) administers the Farm Labor Survey (FLS), which serves as the basis for the AEWRs paid to seasonal agricultural guestworkers working under the H-2A visa program. The AEWRs were originally implemented to help prevent wage depression that might occur from foreign workers being employed by domestic farm employers. The original purpose of the FLS was to provide “the basis for employment and wage estimates for all workers directly hired by U.S. farms and ranches (excluding Alaska).” The FLS was not designed to establish wage standards for the H-2A program. Additionally, the FLS does not survey farm labor contractors or other types of indirect hire farm employees, such as those that may be hired by a farmer to perform tilling or custom harvesting. The FLS surveys farmers in 18 Farm Labor Survey regions, excluding Alaska. All the regions contain more than one state except for California, Florida and Hawaii. The farm labor survey regions can be seen in Figure 1.

The FLS gathers data from farms in April and October and collects information about reference weeks that include the 12th day of the month in January, April, July and October. The FLS provides an estimate of the average gross hourly earnings for each survey region. In practice, survey respondents report total gross earnings paid to employees for the reference period and the total number of hours worked. The average gross hourly earnings of a single employer is calculated by taking the gross earnings paid and dividing by the total number of hours as follows:

Industry groups have argued that the estimated AEWRs exceed the actual local market wages. This has sparked new interest in the H-2A program rules and the methodology used to calculate them. Some factors that could potentially cause the gross hourly earnings estimate to overstate an hourly wage value include bonuses, health coverage, and paid sick leave, which are payments that enter into the gross earnings with no corresponding increase in hours worked. For example, according to the National Agricultural Workers Survey, an increasing share of employees in the Lake States Region have received sick pay benefits over the past couple of decades (See Figure 2). In the FLS, farmers are instructed to report insurance in the gross hourly earnings and the usual hours worked for individuals on paid leave, but industry sources claim that farmers often fail to understand these kinds of details when they fill out the survey. Failing to adhere to the instructions could cause farmers to overstate the gross hourly earnings.

The Farm Labor Survey is a voluntary survey, and a significant number of farmers who receive the survey do not complete it. In the Lake States Region, the response rates have dropped from about 65% in 2012 to about 40% in 2023 (see Figure 3).

The wage estimates are calculated using a weighted average of the data values that survey respondents provide as a method to correct for bias that could result from non-response. For example, suppose there are 1,000 farms in a region and the FLS intends to receive a completed survey from 200 of them. If all 200 of those farms complete the survey, each response would represent 5 farms (200 x 5 = 1,000). However, if only 100 farms answer the survey, then each farm that responds would get a weight of 10 in the sample (100 x 10 = 1,000). Thus, when the response rate is only 50%, the farmers who respond to the survey get twice the initial weight they would have otherwise received before other adjustments are made. Survey responses are also subject to a second “calibration” weighting algorithm to adjust to control metrics, which are supposed to account for farm type and economic class.

In 2024, the AEWRs ranged from a low of $14.53 in the Southeastern Region to a high of $19.75 in California (see Figure 4). In 2023, Michigan’s AEWR increased by $1.97 to $17.34, and it increased by $1.16 to $18.50 in 2024.

Recently, Congressman John Moolenaar (R-Michigan) introduced the “Supporting Farm Operations Act” (HR 7046), which would freeze the AEWRs until the end of 2025. Similar provisions for freezing the AEWR have been included in the “Farm Workforce Modernization Act,” which also has a number of other provisions that would change conditions in farm labor markets.

The Farm Workforce Modernization Act failed to pass through the U.S. Congress in 2022 but was reintroduced in 2023. For more information about the Farm Workforce Modernization Act, refer to canr.msu.edu
