An appreciation of walking to the polls

During my years in Milwaukee, I’ve lived in 4 different neighborhoods. The walking distances to my wards’ polling places have been as follows: 0.2 miles, 0.2 miles, 0.3 miles, and roughly 400 ft. Walking has always been the simplest way to cast my ballot.

This is true for many Milwaukeeans. Compared to most parts of America, including most major cities, Milwaukee excels at making the polls convenient to access.

Over 56% of houses are within half a mile, or a 10 minute walk, of their designated election day polling place. And I’m not counting distance as the crow flies. This is the distance it takes to walk on streets and paths accessible to pedestrians.

Specifically, I calculate that 12.4% of Milwaukee houses are located fewer than 5 minutes from their polling place by foot. Another 44.1% are within a 5-10 minute walk; 27.4% are a 10-15 minute walk away; and just 16.1% are further.

For these calculations, I assume that it takes 1 minute to walk 80 meters, or 262 feet. This works out to 5 minutes per quarter mile, a common standard for walkability.

For instance, here are Milwaukee wards 240 and 285, both of which vote at the Humboldt Park Pavilion in the Bay View neighborhood. Together, these two wards have about 2,300 registered voters living in 1,600 housing units.

  • Because the polling place is in the middle of the park, only a tiny sliver of houses, about 1%, are within a 5 minute walk. This area is shown in purple.
  • Over half, 54%, are in the blue area, which is a 5-10 minute walk from the pavilion.
  • Another 39% are 10-15 minutes away, shown in green.
  • The remaining 6% of houses are in the yellow fringes of the two wards, where walking to the pavilion takes 15 minutes or more.

Here is another polling place, the Clinton Rose Senior Center, near the intersection of King Drive and Burleigh St. This location also serves about 1,600 homes, but more of them are apartments. In fact, 12% of the housing units are within a 5 minute walk, 71% are within 5-10 minutes, and the remaining 17% are 10-15 minutes away.

As you might expect, polling places are closest together in the most densely populated sections of the city. Many of the areas which appear poorly covered on the map are not actually populated—this includes the industrial Menomonee Valley, the port, the airport, and many large parks and cemeteries.

Exceptions include the far north and northwest sides, where few residents live within convenient walking distance of their polling place. Here the normal street grid breaks down, and many people live in subdivisions with poor pedestrian connectivity. The population is also less dense, so individual wards are larger.

The citywide map also reveals some wards which are physically much closer to a different polling place than their own. In these cases, it might be possible to better optimize ward-to-polling place assignments.

Overall, access to polling places is fairly even across the city’s racial or ethnic groups. Using 2020 census data, I estimate that 52% of Black, 57% of white, 63% of Hispanic, and 52% of Asian residents live within a 10 minute walk of their polling place. Conversely, those living 15 minutes away or further includes 18% of Black, 16% of white, 11% of Hispanic, and 22% of Asian residents.

Proximity is highest for Latino Milwaukeeans because their numbers are highest in the densely populated near south side. In contrast, much of Milwaukee’s Asian population lives in the less dense far north and northwest sides of the city.

My methodology is too detailed to easily replicate across the United States, but fortunately the federal government collects information about polling places after each election through the biennial Election Administration and Voting Survey. I downloaded the 2022 data and compared the number of registered voters with the number of polling places in each jurisdiction.

Among the largest 500 jurisdictions in the country, Milwaukee ranked 51st for the most polling places per registered voters. There was one polling place for every 1,661 registered voters in 2022. The median, across the largest 500 jurisdictions, was one polling place for every 3,073 voters.

There is a lot of variation in this metric. Cities in Pennsylvania score especially well, holding 9 out of the top 10 spots. Philadelphia County had 630 voters per polling place, Allegheny County 710.

In contrast, most California cities have few polling places for their size. Los Angeles County had just 640 election day polling places in 2022, one for every 11,581 registered voters. For San Diego County it was one for 11,002 voters, for Orange county 11,267.

Milwaukee also provides proportionally more polling places than other cities in Wisconsin. By necessity, small towns often have higher rates of polling places per capita. But Milwaukee has a higher rate of polling places than all of the other 30 largest cities in the state. The largest community with more per capita than Milwaukee is Stevens Point (pop. 26,000).

Election administration is an increasingly difficult job, subject to conspiracy theories and threats of violence. It’s worth remembering and appreciating that, in Milwaukee, voting is still made admirably easy. For most Milwaukeeans, their polling place (and the opportunity to register) is just a short walk out their front door on November 5th.

How I did this

See this GitHub repository for detailed code and data.

I downloaded data from OpenStreetMap, subsetted pedestrian-friendly streets and paths, then converted these paths and their nodes into a network. An advantage to using OSM data (in addition to its being free) is that it includes informal paths, not just strictly official walkways as Google Maps generally does.

I used Jeremy Gelb’s excellent spNetwork R package to calculate isochrones around each polling place. The original isochrone just consists of lines, so I converted each isochrone to polygons using a minimum concave hull algorithm implemented in the concaveman R package. Finally, I subsetted each of these isochrone polygon sets to just the ward boundaries served by each polling place.

I combined all these individual polling place polygon isochrones, intersected them with the centroid coordinates for each parcel in the city, and aggregated the number of residential units in each.

New research investigates the cost of housing in the Milwaukee metro

The Lubar Center’s latest research project takes a careful look at how housing affordability has changed in the Milwaukee metro in the early 2020s.

Our article, “Can a typical worker still buy a house in the Milwaukee metro? Increasingly, no,” was published in the Milwaukee Journal Sentinel on October 9, 2024. Journal Sentinel business reporter Genevieve Redsten also contributed an article to the series, “Homeownership is less attainable in the Milwaukee area. Why new construction hasn’t been part of the solution.

Our research uncovered much more than could fit in a single story. We have shared additional resources in this web report. It includes more methodological details about our calculations and statistics for individual municipalities in the four-county Milwaukee area.

Previously, we’ve written about how the subprime mortgage crisis and the end of the residency requirement contributed to plummeting owner-occupancy rates in the City of Milwaukee. Home values fell to very low levels in Milwaukee, while rents remained relatively elevated. Consequently, home-ownership was far more cost effective than renting for many families. Meanwhile, rents–particularly in poor neighborhoods–were quite profitable. This profitable potential eventually brought Milwaukee (and similar rust belt cities) to the attention of private equity-backed corporate landlords in the late 2010s and early 2020s.

Those same years saw owner occupancy finally begin to recover in Milwaukee. Owner-occupancy grew slightly in 2019, the first year-over-year increase since 2005. These circumstances combined to foster fierce competition between would-be homeowners and out-of-state investors, particularly in majority Black neighborhoods on the city’s north side.

Since 2022, the market has cooled off. Home prices are still sky high, and increased interest rates have driven the monthly cost required to buy a house even higher. But high interest rates have also changes the calculus of corporate investors. All three of the large private equity backed firms operating in Milwaukee’s rental market have stopped buying and started selling in the past two years. For the first time since the subprime mortgage crisis began, the net number of homes owned by an out-of-state landlord actually declined in the City of Milwaukee during 2023, and that slight decline continued into the beginning of 2024 as well.

Net levels of owner-occupancy continued to grow in 2023 and 2024, albeit at a much slower pace than the preceding several years. It’s no wonder why the market has cooled. Owner-occupancy is far less attainable for many workers, as our latest article discusses in detail. Also, the cost-benefit analysis of owning a home versus renting has shifted. In 2020, we calculated that a typical single family home was cheaper to own than rent, even when factoring in the same kinds of maintenance cost assumptions used by professional property managers. That is no longer true in 2024.

Here is an even simpler comparison. This graph shows the average monthly rent in Milwaukee in blue and the monthly payment needed to buy the average house in red. Before 2018, the PITI (principal, interest, taxes, and insurance) needed to buy the average Milwaukee house was cheaper than the monthly rent for the average apartment (of any size). The two costs were about tied from 2018 through 2020. Since then, the relative cost of owning has skyrocketed, while rents have grown more modestly. “From 2019 to 2024, the monthly costs needed to buy an average home in the city of Milwaukee grew by $854 or an increase of 83%. The average monthly rent grew by $316, or 31%.”

These comparisons of monthly cost ignore the equity accrued by homeowners. This equity is substantial for homeowners who bought during the 2010s, and those owners also benefit from the low interest rates they either initially received or refinanced into. While increased home values exclude a growing number of workers from the home-buying market, they are a windfall for incumbent owners. We estimate that someone who bought the average house in Milwaukee in 2019, paying 5% down, has accrued an average of $78,000 in equity.

Milwaukee remains more affordable than the great majority of major American cities, but home-buying has become far more difficult, even impossible, for many workers. And the financial benefit to buying a house instead of renting one is no longer as straightforward as during the late 2010s.

Recent birth counts point to rapidly shrinking school enrollment in Milwaukee

Many things affect a school (or district’s) enrollment, but the most important is simply how many children live there.

In Milwaukee, recent birth trends point to a future of dwindling class sizes, beginning in elementary school and working their way up through the higher grades. Absent a spike in the birth rate or a big change in migration, the three sectors—district, charter, and private—will find themselves fighting over a shrinking pie.

Across the 1990s, the number of babies born fell by 13%. Then, the trend stabilized, even growing slightly, until the Great Recession. 773 fewer babies were born in 2010 than 2009, and annual declines continued after that. From 2009 to 2019, the number of births fell by 17%.

The COVID-19 pandemic caused a drop in births similar to the Great Recession a decade prior. Births fell by 540 in 2020, 439 in 2021, and 358 in 2022. Losses stabilized in 2023, when the preliminary count shows 7,905 births, still 14% lower than prior to the pandemic.

During the 2010s, schools across all sectors reaped the benefits of Milwaukee’s stable birthrate during the 2000s. Many of the twelfth-graders who graduated this year were born in 2006. Since then, the annual number of births has dropped by 31%.

In the next graph, I compare the number of first graders entering any school in Milwaukee (district, charter, or private) with the number of babies born six years prior. Subsequent first grade enrollment is lower than births because more young families move out of Milwaukee than move into it. However, the size of the gap has remained fairly steady across the 19 school years for which I have data.

In every school year, the number of first graders enrolling has been 21% to 15% lower than the number of babies born 6 years ago. In other words, first grade enrollment has always been between 79% and 85% of the total births 6 years prior. In 2023-24, the figure was 83%, and in 2022-23, 81%.

Because of this stable relationship between births and subsequent first grade enrollment, we can use recent births to forecast the size of future first grade classes.

In the 2023-24 school year, 7,956 kids enrolled in first grade at any school within city limits. Six years prior, about 9,568 kids were born in the city. The children who will enroll in first grade in 2029-30 have already been born. In Milwaukee, they number 7,902.

If Milwaukee retains young families at the best rate from our recent past, it would still mean a decline of 16% in the number of first graders over the next 6 years. Retaining families at the worst rate would result in a 22% reduction. The simple linear model I use in the above graph predicts a 19% drop.

Again, these predictions are not based on a forecast of future birth rates; they are based on the number of babies who have already been born. Some combination of retaining more young families and attracting more migrants (domestic and international) could alter this trajectory. But the current path clearly points to a drop of nearly 20% in the number of first graders by the end of the decade. That decline will then work its way through elementary, middle, and high schools over the 2030s.
