How Philadelphia's Minimum Wage Compares With Other U.S. Cities
Lexey Swall for The Pew Charitable Trusts


The notion of raising Pennsylvania’s minimum wage—and thereby Philadelphia’s—has been a topic of considerable debate over the past year, both in the state Legislature and elsewhere. As of Jan. 1, 2020, Philadelphia’s minimum wage was $7.25 an hour, where it has remained since 2009. The rate—which is also the federal minimum—is set by the state, and the city has no authority to change it.

Responding to a nonbinding ballot question in May 2019, Philadelphia voters voiced overwhelming support for a $15-an-hour minimum. And the city government has raised the minimum for its own workers, as well as for city contractors and subcontractors, to $13.25, with plans to gradually increase it to $15 by mid-2022.

To help inform the conversation, The Pew Charitable Trusts set out to determine how Philadelphia’s minimum wage compares with the rate in other major cities and to take a detailed look at how many Philadelphians have been getting paid that amount—and who they are.

The research found that a majority of major U.S. cities have higher minimums than Philadelphia’s, some substantially higher, although 14 of the 31 cities studied for this brief also are at $7.25. When the overall level of wages in each of the metropolitan areas that include those cities is taken into account, Philadelphia has what is effectively the lowest minimum of any of those cities. This is the result of Philadelphia’s low minimum, the relatively high wages paid throughout the region, and a higher cost of living than in many of the other cities with the same $7.25 hourly rate.

According to data from the U.S. Census Bureau’s American Community Survey (ACS), an estimated 9% of all Philadelphians age 16 or older working in Pennsylvania and receiving wages or salaries from private employers or state or local government—about 44,000 individuals—were earning an hourly average of $7.25 or less in the five-year period ending in 2018, the most recent years with detailed data available. Of that number, approximately 21,000, or 4% of Philadelphia workers, worked full time and year-round at that rate. These estimates likely include some workers who are not covered by the minimum wage or whose employers did not comply with the law.

Relative to the city’s overall workforce, residents earning $7.25 or less were disproportionately nonwhite or Hispanic, young, and lacking a college degree. Sixty-three percent of all Philadelphians earning the minimum wage or less worked in four sectors: accommodation and food services, retail trade, health care and social assistance, and educational services.

As the inflation-adjusted value of the minimum wage has declined over time, the share of those earning $7.25 or less has fallen from roughly 11% of Philadelphians working in Pennsylvania in 2010 to about 8% in 2018. An additional 7% made $7.26 to $9.50 per hour.

With many low-wage workers and the sectors that employ them being hit hard by the COVID-19 pandemic and its economic fallout, it remains to be seen what shape the minimum wage conversation will take once it resumes in earnest.

Philadelphia’s minimum wage compared with those of other cities

The minimum wage in Philadelphia remained at the federal figure of $7.25 per hour as of Jan. 1, 2020.1 States have the authority to raise their minimums above that level, and 29 of them, plus the District of Columbia, have done so.2 Many cities, particularly those where overall wages are relatively high, have raised their minimums above their state baselines. But in 28 states, including Pennsylvania, state law prevents local jurisdictions from doing so, a policy known as pre-emption.3

Figure 1 shows the minimum wage in 31 cities, including nearly all of the nation’s largest, regardless of whether they are subject to state pre-emption or whether the minimum applies locally or statewide.4 The highest minimums are $16.39 in Seattle; $15.59 in San Francisco; $15.25 in San Jose, California; and $15 in New York. The rate is $14 in Washington, D.C.; $12.75 in Boston; and $11 in Baltimore. Nearly all of the highest minimums are local rates; Washington state has the highest state minimum, at $13.50.

Notably, the poorest cities within this comparison group—those with poverty rates higher than 20%, which includes Philadelphia—are all in states with minimum wage pre-emption, and almost all have a $7.25 minimum wage. The exception is Detroit; Michigan’s statewide minimum is $9.65.

To compare minimum wages in places with different levels, economists commonly use the Kaitz index, a locally adjusted minimum wage metric calculated by dividing the minimum by the local median. In this case, each city’s legal minimum was divided by the metropolitan area’s median wage.5 The lower the city’s minimum compared with regional wages, the lower the index.6 At 0.35, Philadelphia’s Kaitz index is the lowest among all large cities because of both the city’s low minimum wage, $7.25, and its relatively high regional hourly rate, $20.47. (See Figure 2.)

Of all large cities with a $7.25 minimum, Philadelphia has the highest regional median hourly wage. Other cities with comparable regional rates have higher minimums; in San Diego, for instance, where the regional median is $20.86, the city minimum is $13.

The minimum wage in Philadelphia also buys less than it does in other large cities around the country. Dividing the minimum by a measure of regional consumer prices, the U.S. Bureau of Economic Analysis’ regional price parity index, Philadelphia has the lowest minimum wage among large cities when adjusted for the local cost of living.7

Inflation has caused the real value of Philadelphia’s minimum wage to fall by 16% since it was last raised in 2009; then, it was worth $8.64 in 2019 dollars. By contrast, many of the largest cities in the country have seen the real value of their minimum wages, some of which are indexed to inflation, grow during the same period, when many cities and states enacted legislation granting an increase. (See Figure 3.)

Who earns the minimum wage in Philadelphia?

Roughly 9% of Philadelphia residents, or approximately 44,000 people who worked within the city limits or anywhere else in Pennsylvania—where the minimum wage would be the same—earned an average hourly rate of $7.25 or less during the five-year period ending in 2018, the most recent years with detailed data available.8(See Figure 4.) Methods for estimating earnings are described in Appendix A.

Less than half of those earning the minimum wage or less, about 4% of Philadelphia residents, worked year-round at full-time jobs.9 Workers may have received less than $7.25 an hour for a variety of reasons, including misreporting (as these values were self-reported), imperfect compliance with the law, exemption from the minimum wage, and imprecise estimates.10 An additional 8% of workers made $7.26 to $9.50 per hour—a proposed minimum wage debated by the Pennsylvania Legislature in late 2019—for a total of 17% earning $9.50 or less.

The cumulative percentage of residents earning various rates or less is shown in Figure 4. Looking instead at people working in Philadelphia, regardless of where they lived, roughly 8% made the minimum wage or less as of 2018.

The percentage of employed Philadelphians earning the minimum wage or less has declined slightly in recent years, falling from roughly 11% in 2010 to about 8% in 2018. (See Figure 5.)

Relative to all Philadelphians working anywhere in the state, workers earning the minimum wage or less were disproportionately likely to be nonwhite or Hispanic, young, and lacking a college degree. Fifty-seven percent of them were female; women represent 54% of the overall wage-earning population. (See Figure 6.)

Forty-five percent were black, 10% were Asian, and 18% were Hispanic (of any race)—all higher than their proportions among all earners. Workers making $7.25 or less skewed young but were distributed across the age spectrum. Only 7% were teenagers, but 24% were 20 to 24 years old, and an additional 30% were ages 25-34. Nearly 58% were 25 to 54 years old, a range often thought of as prime working age.

The majority of workers earning the minimum wage had no college education, though 31% had attended college but had not graduated, and 16% had a bachelor’s degree or higher. Of those ages 16-24, some 54% were currently in school.

Most Philadelphia residents earning the minimum wage or less were born in the U.S. But relative to the city’s overall working population, a disproportionate number of them were immigrants (24%) and were either single or married but not living with their spouses (81%). (See Figure 7.)

Philadelphia residents earning the minimum wage or less were also concentrated in households with low incomes; 50% of workers earning $7.25 or less were in households with incomes under $35,000, compared with 17% of all workers.

Four sectors of Philadelphia’s economy accounted for nearly 63% of city residents earning the minimum wage or less: accommodation and food services, health care and social assistance, retail trade, and educational services. In two of those sectors, the percentage of workers making the minimum was disproportionate to the sector’s overall share of local employment: Accommodation and food services employed 20% of all residents making $7.25 or less but only 8% of earners overall, while retail trade employed 16% of workers making the minimum or less and 10% of workers overall. (See Figure 8.)

The most common occupations among workers making the minimum wage or less were cashiers (nearly 9%); nursing, psychiatric, and home health aides (more than 5%); chefs and cooks (more than 5%); retail salespeople (more than 4%); waiters and waitresses (nearly 4%); and personal care aides (nearly 4%). (See Figure 9.)

The demographics of the population earning $7.25 or less shifted slowly from 2006 to 2018, reflecting changes in the makeup of Philadelphia’s overall population during that period. Hispanics, individuals ages 25-34, and those with a bachelor’s degree or more education all increased as a share of those earning the minimum wage or less and as a percentage of all workers.

Workers earning the minimum wage or less were not a homogenous group, so a statistical technique known as cluster analysis was used to identify distinct groupings of Philadelphia workers making the minimum or less based on their demographics and household incomes.11

The analysis found that workers could be divided into six major clusters. (Detailed cluster characteristics can be found in Appendix B.) The largest cluster included primarily male, African American workers with limited education and an average age of 29, but others were quite different. For instance, two clusters were made up primarily of immigrants, one Asian and one Hispanic, with a high school education or less schooling. Another cluster captured African American women with an average age of 55 and a high school education, who may face limited opportunities for transitioning into higher-paying jobs. And the final two clusters collectively included young workers—mostly African American or white—with some college education, who may be working low-paying jobs temporarily before continuing to advance their educations.

Geographically, Philadelphia residents earning $7.25 or less were most concentrated in North, Eastern North, and Southwest Philadelphia, areas in which 12% or more of workers were earning the minimum wage or less. (See Figure 10.) These were also areas with relatively higher densities of residents living in poverty.12


Over time, inflation has eroded the real value of the federal minimum wage, which is also Pennsylvania’s minimum, and that has effectively lowered the buying power of the minimum in Philadelphia.

In a region with relatively high wages overall and a comparatively high cost of living, this trend has left Philadelphia with what is in effect the lowest wage floor of any large American city. By 2018, the percentage of Philadelphians earning the minimum or less had dropped to its lowest level since 2006.

Economic conditions and policy decisions regarding the minimum wage will determine the trajectory of those trends in the post-COVID-19 era.

Appendix A

Methodology for earnings estimation

Hourly earnings were estimated as follows. The population of civilian residents of Philadelphia age 16 or older who worked in Pennsylvania and had income was filtered to include those who reported working for more than 13 weeks (including the previous one) and more than 10 hours per week during the previous year. The intention of this filtering step was to capture workers who were actively attached to the labor market (roughly 85% of workers). Workers who reported working 99 or more hours per week (roughly 0.1%) were excluded, as their average earnings could not be calculated. To exclude those not covered by minimum wage laws, workers were further restricted to those paid a wage or salary by a private or nonprofit employer, or by state or local government (94% of filtered workers). The self-employed (3%) and federal workers (3%) were excluded, as were unpaid family workers (less than 1%).

Hourly earnings were calculated by dividing self-reported values for annual wage and salary income, which had been adjusted to the amount that it would have been if it had been earned entirely during the calendar year, by the product of the usual hours worked per week and the number of weeks worked during the previous year, where the number of weeks worked was estimated as the midpoint of the interval reported in the U.S. Census Bureau’s American Community Survey (ACS). Outliers (less than 0.1%) earning less than $0.50 an hour in 1989 dollars were dropped from the analysis.

These methods are based on those described in I. Perry, S. Thomason, and A. Bernhardt, “Data and Methods for Estimating the Impact of Proposed Local Minimum Wage Laws” (2016),, and used elsewhere, though the use of self-reported survey data along with the indirect method of estimating earnings creates the possibility for misreporting and necessarily results in some imprecision in these estimates.

An alternative data source for estimating the distribution of Philadelphia residents’ earnings is the Current Population Survey (CPS), sponsored jointly by the U.S. Census Bureau and the U.S. Bureau of Labor Statistics. The CPS contains a much smaller sample size, making the ACS more suitable for characterizing the population earning the minimum wage or less. The CPS also lacks data on residents’ place of work, making it impossible to determine what fraction of earners work in Pennsylvania rather than in adjacent states where the minimum wage is higher than $7.25. The CPS does, however, allow respondents to directly report their hourly rate, potentially making those values more accurate. Based on CPS data for 2014-18, roughly 4% of Philadelphia resident civilian workers age 15 or older and paid a wage or salary by a private or nonprofit employer, or by state or local government, earned $7.25 or less, and 16% made $9.50 or less, according to IPUMS-CPS, University of Minnesota, Due to data limitations, this population was not filtered to exclude workers based on the number of hours or weeks worked.

Exemptions from the $7.25 minimum wage include domestic workers, some seasonal workers, some students, and trainees.
