Florida State Senator Joe Gruters recently introduced Senate Bill 168, which would effectively force local and state law enforcement to become federal immigration agents. Along with House Bill 527, SB 168 would ban policies that limit local cooperation and information-sharing with federal authorities on immigration matters. These bills would create a hostile environment in Florida, potentially causing contributing members of the immigrant community to leave the state as a result. These bills could also result in significant economic losses for the state, and would also threaten key parts of Florida’s workforce in industries like agriculture and construction.

If these bills become law, Florida would be following Arizona’s example.  In 2010, the Arizona Legislature enacted SB 1070, a “show me your papers” law that gave broad authority to local law enforcement to act as immigration agents and target potential undocumented immigrants. Subsequent studies have shown that Arizona’s law led to a large decline in tax revenue and significant struggles for several key industries in the state due to the estimated 10 percent of its undocumented population^[1] that left the state after the law was passed. Many of these immigrants had been working in hard to fill jobs in construction, hospitality, and other key industries.

The Arizona experience should be a cautionary tale. Like in Arizona, undocumented immigrants in Florida are overwhelmingly employed. According to New American Economy, 85.8 percent of undocumented immigrants in Florida are of working age (ages 16 to 64). They pay $1.7 billion each year in taxes, including more than $543.2 million in state and local taxes, and hold $13 billion a year in spending power to inject into the local economy. The costs of losing a significant portion of these workers could be substantial for Florida’s economy.

This brief models what the economic costs would be if SB 168 and HB 527 were signed into law and 10 percent of the state’s undocumented population were to leave as a result. To be conservative, it also models the impact if Florida experienced just half the immigrant exodus – 5 percent.

In either of the two cases modeled – the Arizona-style 10 percent immigrant exodus or the more conservative 5 percent exodus – the state would risk losing millions of dollars in taxes and up to $3.5 billion in state gross domestic product in just one year.

• If 10 percent of undocumented immigrants leave Florida, the state will lose $76.7 million in federal taxes, and $44.7 million in state and local taxes.
• In total, Florida will lose $3.5 billion in Gross Domestic Product (GDP).
• This 10 percent includes an estimated 44,598 employed workers, whose departure will reflect a $1.4 billion loss in wage earnings. State-wide, business owners in industries such as construction, restaurant and food services, and traveler accommodation will be greatly affected.
• The state will also lose an additional 27,395 jobs that are dependent on undocumented immigrant consumers and supporters of industry. These indirect job losses will result in another $911.4 million loss in wage earnings for the state.

The economic loss as it relates to jobs, earnings, taxes, and GDP is proportional to the number of undocumented immigrant workers that would leave the state. For instance, if 20 percent of undocumented immigrants leave Florida, the economic cost will be twice the above numbers.

Accordingly, we also estimated the economic loss as it relates to jobs, earnings, taxes, and GDP over a one-year period in an alternative scenario where 5 percent of undocumented immigrants were to leave Florida. The five percent estimate is based on the assumption that passage of SB 168 and HB 527 may have a lesser impact compared to Arizona’s SB 1070 law (see detailed methodology below).

• If 5 percent of undocumented immigrants leave Florida, the state will lose $38.4 million in federal taxes, and $22.4 million in state and local taxes.
• In total, Florida will lose $1.8 billion in Gross Domestic Product (GDP).
• This 5 percent includes an estimated 22,299 employed workers, whose departure will reflect a $700 million loss in wage earnings. State-wide, business owners in industries such as construction, restaurant and food services, and traveler accommodation will be greatly affected.
• The state will also lose an additional 13,698 jobs that are dependent on undocumented immigrant consumers and supporters of industry. These indirect job losses will result in another $455.7 million loss in wage earnings for the stat.

In either scenario, the losses detailed above are significant. Because of the role undocumented immigrants play in the state labor market—including their critical role in particularly labor-intensive jobs—U.S.-born workers, with different skill sets and professional interests, would only fill a small number of the positions vacated by immigrants.^[2] Some businesses may have to close all together because they can’t find the appropriate workforce to fill vacant positions, leading to job losses for the U.S.-born individuals employed by those businesses. Economic activity will decrease across the board, having a dramatic effect on U.S.-born workers and many of the state’s important industries that depend on paying customers, such as retail and service industries.

Methodology for Estimating Potential Economic Cost of Florida’s Senate Bills 168 and House Bill 527

To estimate the potential economic cost of the passage of SB 168 and HB 527, we first obtained 2017 American Community Survey (ACS) one-year data using the Integrated Public Use Microdata Series (IPUMS) portal. We then applied the methodological approach outlined by Harvard University economist George Borjas to arrive at an estimate of the undocumented immigrant population in Florida.^[3] We identified the top five industries in which undocumented immigrants worked, and created a new category that lumps all undocumented workers working in industries other than the top five.

By using the above data and industry multipliers from the Regional Input-Output Modeling System (RIMS II), we estimated the total loss in jobs, worker earnings, and Gross Domestic Product (GDP) over a one-year period in Florida if 10 percent of the undocumented immigrants leave the state as a result of the proposed bills.^[4] RIMS II is a standard economic impact tool developed by the Bureau of Economic Analysis and is widely used in economic impact studies by government agencies, corporations, and researchers.

Our model for the economic impact on Florida if 10 percent of undocumented immigrants leave the state is based on a study by Gonzalo Sanchez of Texas A&M University.^[5] His research on Arizona SB 1070, a similarly controversial legislation requiring state law enforcement to enforce federal immigration law in Arizona, found that noncitizen Hispanics—a proxy used to estimate the state’s undocumented population—decreased by 10 to 15 percent after the bill passed. We argue that, although the passage of SB 168 and HB 527 may not have the same legal implications as Arizona SB 1070, it would create a similarly hostile political climate that would encourage undocumented immigrants to leave Florida. However, we understand the likelihood that the impact of the bills on the undocumented immigrant population may be smaller than what Sanchez found for Arizona SB 1070, so we also express our results under a scenario that assumes that only five percent of undocumented immigrants leave Florida.

The RIMS multipliers provided the information we needed to calculate the direct, indirect, and induced economic cost in each industry. The direct cost comes from the impact on the top 10 industries that would be directly affected by the loss of undocumented workers, and the indirect cost is the impact on the industries that provide goods and services to the top 10 industries. Induced cost, on the other hand, is the impact on industries affected across the board because of loss of consumption from undocumented workers. When estimating the economic cost, we chose the RIMS multipliers corresponding to the top five industries that undocumented immigrants worked in. For the category that lumps the rest of the undocumented immigrant workers together, we apply the smallest multiplier among the rest of the industries to be conservative in our estimates.

Aside from the loss of jobs, worker earnings, and GDP, we also calculated the potential loss in federal and in state and local tax revenues over a single year if 10 percent of undocumented immigrant workers leave the state. To estimate the tax contributions of 10 percent of Florida’s undocumented immigrants, we randomly selected 10 percent of the undocumented immigrant population in Florida, then estimated tax contributions for that random 10 percent sample.^[6] We repeated this estimation process 100 times, then took the minimum tax estimation out of the 100 iterations for a conservative estimate. We estimated state and local taxes using the tax rates estimates produced by the Institute on Taxation and Economic Policy (ITEP).^[7] For federal tax estimates, we used data released by the Congressional Budget Office in 2014 and calculated federal taxes based on the federal household income tax brackets.^[8]
