Technical Troubleshooting Guidelines

PolicyMap Does Not Load or Run Properly

In the event that PolicyMap does not load and run correctly, there are several technical troubleshooting activities that can be performed to resolve the problems.  Given that the application is Internet-based, the issues that cause it to fail to run are almost always traced to a faulty or interrupted connection between the end computer and the servers that run PolicyMap.  Some examples of these types of issues are shown in the screenshots below.

In the first example, neither the search box nor the map will load:

Did you know can see data changes across years. The legend will allow you to view trends; on the Maps, choose %Ch in the change variable section, while on the Table choose the “View Trends Across Years”. Subscribers can see trends for most US Census datasets, comparing against Claritas 2007 estimates and 2012 projections.

Not all data layers have the options to see a trend across years, but always look at the legend for the %Ch option.

The latest mortgage statistics from the Home Mortgage Disclosure Act (HMDA) for 2007, along with data for 2004, 2005, and 2006 are now available and mapped on PolicyMap.
See how the median home purchase amount has changed over time in your community, where subprime lending is concentrated, where buyers took out two loans to purchase their home, and more. Find this in the Mortgage Originations tab in the Add Data Layer menu.

A note about this data:

  • According to HMDA, a number of banks that reported in previous years, did not report in 2007 for financial reasons. As a result, comparing 2007 data to previous years may be more problematic this time around than previously. We’ve done a series of percent change calculations with the HMDA data, so we just want to caution that some of the decline, for example, in subprime lending may have to do with a smaller number of banks reporting information to HMDA. Look for an upcoming blog entry for 2007 HMDA highlights and more discussion of the data.
  • Also, on the percent change maps, be sure to increase the number of ranges to 8 in the legend, so you can see places where subprime lending went up in purple.

Qualified Census Tracts, Difficult Development Areas and Gulf Opportunity Zones.
Find out if the address or census tract in which you are interested qualifies under one of these categories. Find these maps under the State and Local tab in the Add Data Layer menu. Zoom into your area of interest or use the Set Location bar to type in an address or locate a particular census tract. Use the legend to determine if the address sits within an eligible area or if the census tract qualifies.

Find out how many homes sold, their median sale price and loan to value ratios for block groups, census tracts and counties around the nation. Home sale data is now available for 2006 through Q12008, with trends showing changes from 2001, 2003, and 2005, in PolicyMap. See this data in maps, tables and a unique Home Sale Report. (Home sale data and reports are available to subscribers only.) Visit our Data Directory for a listing of counties with home sale data.

A note about this data:

  • Home sale data for 2008 Q1 for Philadelphia County was not provided by Boxwood Means, as their data provider did not collect Philadelphia home sale data this period. Subsequent releases should include sales data for Philadelphia County.


Coming Next Month!


New Data:

More on Foreclosure Data

Posted under: News/Press Releases,Online Buzz — Tags: , by Phil V. @ 4:12 pm

Before I left for France, I passed along this information from HousingPolicy.org on foreclosure data. That prompted a nice note from Jeff over at PolicyMap, who wrote:

I know you’ve written about PolicyMap.com in the past, and wanted to again recommend it for this topic. As part of the Neighborhood Stabilization Program (NSP), state and local governments will be charged with creating an action plan for allocating the funds. PolicyMap can help officials to identify areas in need and map the local housing markets. In fact, they just uploaded new HUD NSP data sets to make the process easier and more data-rich.

So I checked what he was talking about, and here it is. The PolicyMap blog explains that:

As an organization either applying to HUD for National Stabilization Program (NSP) grant dollars or interested in the program, you know that HUD expects grantees to consider several specific pieces of data in preparing plans and strategies for targeting funds. To make that work easier, we have mapped all that data and made it available for you on PolicyMap, the online data and mapping tool we created to aid public and social investors in understanding places and considering investment strategies. All public data and use of the tool for this purpose is free.

So check it out! Free data is always good. (And keep the information flowing — let me know if you have data to share with community indicators practitioners!)
