Location Affordability Version 2: Better Than the Original

Brand new datasets are great. When HUD’s Location Affordability data came out last year, we couldn’t wait to add it, because of how simply it illustrated the impact of housing and transportation costs on the budgets of various household types.

What’s better than new datasets? When a new dataset is so useful, its creator decides to make it better. And that just happened with Location Affordability. Soon after the original Location Affordability was released, HUD arranged a conference call of the data’s key users, which we participated in. Based on the feedback from that call, HUD made some significant improvements.

Version 2 of Location Affordability uses new methodology to produce more accurate estimates of housing and transportation costs, so this data which was pretty neat to begin with is now even more powerful. The specifics of the update are pretty wonky, but if you’re reading this blog, you’re probably pretty wonky too, so here are the highlights of the new version, according to HUD:

  • Moving to a Simultaneous Equation Modeling (SEM) approach from Ordinary Least Squares regression: SEM better incorporates and accounts for interaction effects on the model’s dependent variables, resulting in a model that has greater econometric validity
  • Adding variables for housing stock: the model now includes variables for percent of single-family detached housing units and the number of rooms per dwelling unit
  • Adding variables for local commercial amenities
  • Splitting population data by tenure (renter vs. homeowner)

And whereas version 1 covered 94% of the country’s population, version 2 covers 100%.

Also, very importantly, the household types have changed significantly. The affordability data is calculated differently for different households according to number of people, income amount, housing needs, transportation needs, and more.

These are the new household types:

HOUSEHOLD TYPE SIZE OF HH INCOME # COMMUTERS
Median-Income Family 4 Median Income for Region 2
Very Low-Income Individual 1 National Poverty Line 1
Working Individual 1 50% of Median Income for Region 1
Single Professional 1 135% of Median Income for Region 1
Retired Couple 2 80% of Median Income for Region 0
Single-Parent Family 3 50% of Median Income for Region 1
Moderate Income Family 3 80% of Median Income for Region 1
Dual-Professional Family 4 150% of Median Income for Region 2

 

This data is free to the public, and is in the Incomes & Spending menu, under “Additional Income & Spending Data”.

New Unbanked Data on PolicyMap!

Have you been to your local bank branch lately? Perhaps withdrawn money from your checking or savings account using an ATM? Many of us who have a relationship with a traditional financial institution may take it for granted, but a lot of people are without access to these institutions. Growing attention is being paid to households who are considered “unbanked,” meaning the household lacks any kind of deposit account at an insured depository institution, or “underbanked,” meaning the household has a checking and/or savings account but has also used alternative financial services (AFS) at least once in the previous year. In light of the growing interest in this area, we are pleased to announce that we have recently added state and metropolitan area level data from the 2011 Federal Deposit Insurance Corporation (FDIC) National Survey of Unbanked and Underbanked Households to PolicyMap.

See Round I Promise Zones on PolicyMap

We recently added areas designated as federal Promise Zones to PolicyMap. What is a Promise Zone? These areas are the first five of 20 total communities to be designated through 2015 by the Obama administration:

  • Choctaw Nation of Oklahoma
  • Kentucky Highlands
  • Los Angeles (Hollywood, East Hollywood, Koreatown, Pico Union and
    Westlake neighborhoods)
  • San Antonio (EastPoint neighborhood)
  • Philadelphia (Mantua neighborhood)

Designation as a Promise Zone does not entail any additional federal grants or funding; instead, HUD, USDA, HHS, DOJ, SBA, and other federal agencies will help local government representatives to coordinate and maximize the impact of existing programs. Of the five places named this year so far, all are home to existing programs or designations such as Promise Neighborhoods, Choice Neighborhoods, and/or Byrne Criminal Justice Innovation Program partnerships. The administration has also proposed a tax incentive for private businesses who locate jobs in these areas.

PolicyMap Geocoder: Now Even More Gooder!

400 North Street, Harrisburg, PA. It’s a simple address. It’s a state office building. People work there. You can mail a letter there.

But for a while, you might have had some trouble finding it on PolicyMap. A couple years ago, we upgraded our geocoder (the process that finds an address on a map) so it was much more flexible in finding addresses typed into the location bar.

The new geocoder featured rooftop geocoding: It knew the precise locations of most addresses in the country. It also featured constant updates, spellchecking capabilities, and alternate street names.

The old geocoder used linear interpolation for geocoding: It knew the streets and addresses at each end of the street, and guessed where the building was based on the address number.

The new geocoder also has linear interpolation, if it can’t find the rooftop. But its interpolation performance left something to be desired. Namely, 400 North Street, Harrisburg, PA. What we found was, the new geocoder was great at finding residential addresses, but wasn’t consistent in finding commercial or government locations. The old geocoder was better at this, but didn’t have all the improvements the new one offered.

This put us in a bind. The new geocoder usually worked better, but the old geocoder was able to find a lot of addresses the new one couldn’t. If only we could somehow have both of them…

So that’s what we did. Now, when you type an address into the location bar (or feed addresses through the Data Loader) it first goes through the new geocoder, and if that fails, then through the old geocoder. Genius! In our tests, this improved our match rates significantly. Crucially, it found 400 North Street, Harrisburg, PA.

Do you need to do anything different? No. Everything will function exactly the same as it used to; you just won’t get to see the “Location not found” error as much.

Map Vocabulary

PolicyMap has two basic types of maps. One has a very simple name, the other is more complicated.

This is a point map:

Pretty simple: the map shows points representing the locations of, in this case, schools.

So what’s this?

The data here represents a geographic area, not just a single point. It’s usually an aggregation of a mass within the area (number of people, percent of families, median dollar amount, etc.), where different colors represent a range of values among all areas. There is a technical term for this: choropleth map. (You’ll notice there’s only one “L” in choropleth; it’s not chloroform.) Map nerds know exactly what a choropleth map is. The problem is, just about no one else in the world has heard of the term, and frankly, it’s not very fun to say.

On PolicyMap, we call these Data Layers. The data is neatly layered underneath the map labels. The problem with this term is you can’t actually have multiple layers of Data Layers (how would you see the multiple colors at once?). Ironically, you can layer as many points as you want onto a point map. So it could be confusing.

Around the office, we call this “thematic data” (as would appear on a thematic map). Unfortunately, that’s not correct either, since a thematic map is any map that shows data, which would include maps with points. Occasionally, you’ll hear us slip this term into conversation, but we have a swear jar we have to drop a dollar in every time we use it.

Sometimes I call this “shaded data”. But we don’t want to imply there’s anything shady about our data.

So remember: Data layers = choropleth map = thematic data (when we slip up) = shaded data. Have a better name for this? Let us know!

Home sale data for 2013 now available on PolicyMap!

PolicyMap recently updated our home sale data to include 2013 transactions. The data include information on how many home sales occurred in your neighborhood, city or county. It also includes the median sales price of those transactions, and the loan-to-value ratio, which compares the value of the first mortgage taken out on a home to the sales price.

Our home sale data is one of the most popular datasets we have because these statistics are so important to understanding the real estate market in an area. Annual data are available from 2006 through 2013, but we also offer a 5-year trend indicator that allows you to look at trends in home sales from 2001 to 2006.

The two maps below compare the 5-year trends in home sale prices in the Washington D.C. Metropolitan area. The first shows the percent change in the median sales from 2001 to 2006. The areas on the map that are darker purple indicate that sales prices have gone up the most – more than a 125% increase in five years. The lighter purple areas on the map also saw increases in sales prices but at lower rates. The pattern in fairly clear; greater sales price increases occurred in the eastern half of Washington DC, in Prince George’s County Maryland (to the east of the City), and some parts south and west of D.C.Map0106 Continue reading

Low Income Housing Tax Credit Data Updated on PolicyMap!

One of our most popular datasets, Low Income Housing Tax Credit (LIHTC) projects, has been updated on PolicyMap! The LIHTC program is an indirect federal subsidy used to finance the development of affordable rental housing for low-income households. It provides tax incentives to encourage individuals, corporate investors, and banks to invest in the development, acquisition, and rehabilitation of affordable rental housing. According to one estimate, the LIHTC program has helped to finance the development of more than 2.4 million affordable rental housing units since its inception in 1986. The data, released annually by the Department of Housing and Urban Development (HUD), now includes all projects that have been placed in service through 2012. Use the map below to explore LIHTC projects in your local area!

Developing an Arts and Culture Hub, with Data

Exploring Our Town

CultureBlocks profiled in Exploring Our Town, NEA’s showcase of best practices

The Philadelphia Inquirer recently showcased a study by Drexel researchers exploring cultural assets in the Mantua, Powelton and West Powelton neighborhoods in West Philadelphia. The report, A Fragile Ecosystem (pdf), describes a neighborhood with lots of resident artists, dense artistic clusters along major commercial corridors, and tons of regional cultural amenities close by. This report was of particular interest to me, as one of this area’s newest residents. (My roommate and I moved in on Sunday. Once I finish hanging curtains and weeding the backyard, it will be home.)

If you open the report and look closely, you’ll see virtually all the facts and figures in the tables and maps come from CultureBlocks, a free arts and culture mapping tool powered by PolicyMap. Personally, I have used this site to scope out the local arts nonprofits, galleries, and meeting places in my new neighborhood. But this data-rich tool isn’t just for the casually interested Philadelphian; it’s a powerful tool for anyone who is interested in cultivating neighborhood cultural amenities, including funders, developers, and local organizations.

CultureBlocks has also been highlighted by National Endowment for the Arts (NEA) in its Exploring Our Town showcase of creative placemaking projects. Exploring Our Town features projects from throughout the U.S. that offer practitioners nationwide examples of successful arts-based community development work.

The NEA profile poses the question, “How can a web tool be developed to help people understand the relationship between cultural engagement and economic development?” One of the issues highlighted in the Drexel report is that public investment in cultural amenities in Mantua/Powelton is comparatively low, even though the area has one of the highest concentrations of resident artists. The availability of this cultural data all in place has made exploring these research questions easier, and may facilitate more cultural partnerships as developments such as the University City High School site evolve. CultureBlocks features data from the City of Philadelphia’s Office of Arts, Culture, and Creative Economy (OACCE) and the University of Pennsylvania’s Social Impact of the Arts Project (SIAP). We will be updating the source data over the next two months. Read more about CultureBlocks on our blog.
