Summerfest has been running since 1968 and is a three-weekend festival on 75 acres at Henry Maier Festival Park. Its recent attendance, economic impact, and operating figures show how large the Milwaukee event is beyond its concert schedule. The figures below identify the relevant year or period and retain the named source for each statistic.

Several figures define Summerfest’s physical and organizational scale:
- Milwaukee World Festival, Inc. was founded in 1965, three years before Summerfest began, according to the Milwaukee World Festival economic impact press release.
- Summerfest has operated since 1968, uses 12 stages, and occupies 75 acres of festival grounds, according to Summerfest About Us.
- The festival is presented by American Family Insurance and features hundreds of performances each year, according to Summerfest About Us.
- Summerfest is produced by an independent private 501(c)(3) corporation, according to Summerfest FAQ.
- The festival is held over three weekends, according to the Milwaukee World Festival economic impact press release.
- Henry Maier Festival Park attracts nearly 1.3 million people annually across events, according to the 2024 Non-Profit Organization Handbook. That figure covers events at the park, not Summerfest attendance alone.
- Summerfest general admission covers the festival grounds and stages during operating hours from noon to midnight, according to Summerfest Tickets.
The combination of a 75-acre site, 12 stages, and a three-weekend schedule helps explain why Summerfest statistics include more than a single attendance total. Some figures describe the festival itself, while others describe the broader festival park season or the nonprofit organization that produces the event.
Attendance and weather
Summerfest attendance has varied substantially in the recent four-year series reported by the Summerfest 2024 attendance report.
| Festival year | Reported attendance | Year-specific context |
|---|---|---|
| 2021 | 409,386 | Attendance reported by Summerfest |
| 2022 | 445,611 | Attendance reported by Summerfest |
| 2023 | 624,407 | Attendance reported by Summerfest |
| 2024 | 555,925 | Six of nine festival days were rain-affected |
The 2024 total of 555,925 was down about 11% year over year, according to the Summerfest 2024 attendance report. The same report says six of the nine festival days were affected by rain, and that 2024 saw the most rain at Summerfest since 2000. Those details provide important context for comparing 2024 with 2023: the attendance difference should be read alongside the reported weather conditions rather than treated as a simple measure of changing interest.
The 2023 total of 624,407 was the highest figure in this four-year set. Attendance was 445,611 in 2022 and 409,386 in 2021. These totals are event-year measurements, not estimates of the park’s annual visitor population. They also should not be combined with the nearly 1.3 million annual visitors attributed to all Henry Maier Festival Park events in the 2024 Non-Profit Organization Handbook.
Summerfest 2024 included more than 600 artists, according to the Summerfest 2024 attendance report. The festival also offered 14 free admission promotions, and 21% of attendees entered through one of those promotions, according to FOX6 Milwaukee coverage of the official release. More than 70,000 free tickets were distributed to the community in 2024, according to the same FOX6 Milwaukee coverage.
Festival scale and programming
The basic Summerfest footprint has remained easy to summarize: 75 acres and 12 stages. The Summerfest About Us source describes hundreds of performances each year, while the 2024 attendance report records more than 600 artists for that festival year. “Performances” and “artists” are different measures, so they are best read as complementary indicators rather than added together.
The three-weekend format is another defining statistic. Summerfest’s operating schedule is spread across nine festival days, as reflected in the Summerfest 2024 attendance report’s reference to six rain-affected days out of nine. A Summerfest 3-day pass is valid on three different days, according to Summerfest Tickets. The same ticket source says a 9-day power pass covers all nine days of the 2026 festival; that is a ticket-validity description for the 2026 offering, not a claim about 2024 attendance.
Summerfest’s presenting sponsor is American Family Insurance, according to Summerfest About Us. The event is produced by an independent private 501(c)(3) corporation, according to Summerfest FAQ. That organizational structure distinguishes the festival producer from the public economic activity measured in the economic-impact studies.
Safety and access also have quantified rules. All Summerfest gate entrants and employees go through metal detection, according to Summerfest FAQ. Bags larger than 9x10x12 are not allowed on the grounds, using the dimensions stated in that source. These are operating policies rather than attendance measures, but they help describe the scale of managing entry across a large, multi-stage festival.
Economic impact and jobs
The Milwaukee World Festival 2023 economic impact press release reports that Summerfest generated $160.3 million in economic impact for the city of Milwaukee in 2023. The same study reports $188.7 million in economic impact for Wisconsin, $14.4 million in state and local taxes in Wisconsin, and $110.2 million in total direct spending during the three Summerfest weekends.
The 2023 study also says Summerfest supported 3,400 total part-time and full-time jobs in Milwaukee. These figures describe the economic impact attributed to Summerfest in the study’s stated geography and year. They are not the same as the more than 2,400 seasonal employees Milwaukee World Festival hired in 2024, a separate operational figure reported by FOX6 Milwaukee coverage of the official release.
The broader Henry Maier Festival Park season produced larger totals because it includes events beyond Summerfest. For the 2023 festival season at Henry Maier Festival Park, the Milwaukee World Festival 2023 economic impact press release reports:
- $182.4 million in direct spending.
- $263.2 million in Milwaukee economic impact.
- 4,300 total part-time and full-time jobs.
- $318 million in economic activity for Wisconsin.
- $22.6 million in state and local taxes.
The difference between the Summerfest-only and full-season figures is a useful geographic and scope distinction. Summerfest’s reported 2023 Milwaukee impact was $160.3 million, while the full festival season’s Milwaukee impact was $263.2 million. The full-season figures include Henry Maier Festival Park events beyond the three Summerfest weekends and should not be presented as Summerfest-only totals.
A separate 2024 Non-Profit Organization Handbook says Summerfest typically generates about $187 million in annual community economic impact. Because that figure is described as typical and annual, it is not a replacement for the measured 2023 results above. It is a broader contextual figure and should be read with its source label and wording intact.
Sponsors, vendors, and seasonal operations
Summerfest 2024 had 64 total sponsors, including 14 new sponsors, according to FOX6 Milwaukee coverage of the official release. The event also had more than 33 additional exhibitors. Its marketplace included 87 vendors filling 132 vendor spaces. The two marketplace counts measure different things: vendors are businesses or participating sellers, while spaces are the occupied locations.
The 2024 event employed more than 2,400 seasonal employees, according to the same FOX6 Milwaukee coverage. That number is a hiring figure for 2024 and should not be substituted for the 3,400 jobs supported by Summerfest in Milwaukee in the 2023 economic-impact study. The latter includes supported part-time and full-time jobs in the study’s economic model; the former counts seasonal employees hired by Milwaukee World Festival.
The event’s community-facing operations also included donations in 2024. FOX6 Milwaukee coverage reports more than 26,000 meals donated for food insecurity support, more than $13,500 worth of hygiene products donated, and more than 4,000 books donated. These are reported donation totals for 2024, and the categories should remain separate rather than being combined into an unsupported monetary or item total.
Community giving and grants
Summerfest’s community programs include both ticket distribution and grant activity. More than 70,000 free tickets were distributed to the community in 2024, according to FOX6 Milwaukee coverage of the official release. That figure is related to, but not interchangeable with, the 21% of 2024 attendees who entered through one of 14 free admission promotions.
The Let the Music Play program had awarded more than 50 grants since its inception in 2018, according to Let the Music Play Music Grants. The program was entering its eighth year in 2025–2026, according to the same source. Its first grants were standardized at $2,500 each. The first-grant amount describes the program’s early standardized award and does not establish the value of every later grant or a total amount awarded.
The 2024 BMO EMpower program funded 11 women and small business owners, according to BMO Summerfest EMpower Grant Program. That source also describes BMO’s EMpower program as a more than $40 billion commitment. The $40 billion figure is the commitment size described by the program source, not the amount distributed through the 2024 Summerfest grant activity.
Taken together, these figures show several different forms of participation: 2024 free-ticket distribution, admission promotions, grants since 2018, an eighth program year in 2025–2026, and 11 recipients in a 2024 grant program. Each number belongs to its own program and time period.
Visitor and volunteer numbers
The 2024 Non-Profit Organization Handbook describes specific staffing requirements for nonprofit concession operations at Summerfest. A nonprofit concession stand may require between 5 and 20 people to operate for between 8 and 12 hours, plus setup and teardown. This is a stated operating range, not a count of all volunteers at the festival.
Volunteers for the nonprofit program must be at least 18 years old, according to the handbook. They must report up to two hours before each event starts, and volunteer lists are due at least 21 days before each event. Organizations must give at least 30 days’ advance notice if they cannot fully participate on one or more Summerfest days. Volunteers must also be able to lift objects weighing up to 40 pounds.
These requirements put practical scale around the nonprofit side of the event. The handbook’s 5-to-20-person concession range, 8-to-12-hour operating range, 21-day list deadline, 30-day notice requirement, and 40-pound lifting requirement are rules for participating organizations rather than measures of attendance or economic impact.
For visitors, the ticket information is similarly specific. General admission covers the festival grounds and stages during operating hours from noon to midnight, according to Summerfest Tickets. A 3-day pass covers three different days, while the 9-day power pass covers all nine days of the 2026 festival. Those ticket definitions help distinguish access products from attendance totals: a pass’s validity describes what a ticket permits, while attendance describes people recorded as entering during a particular festival year.
