This article demonstrates how to use a GIS to process ZIP Code Crosswalk Files. Using a GIS to Geoprocess ZIP Code Crosswalk Files Department of Housing and Urban Development’s ZIP Code Crosswalk Files,” Cityscape: A Journal of Policy Development and Research, Volume 20 Number 2, 277 – 294. Department of Housing and Urban Development (HUD) United States Postal Service ZIP Code Crosswalk Files when working with disparate geographies. The following article demonstrates how to more effectively use the U.S. Though often used for mapping, spatial analysis, and data aggregation careful attention is required when interpreting ZIP Code data relative to other administrative geographies. As a result, ZIP codes that only serve PO Boxes will not appear in the files. Please note that the USPS Vacancy Data is constructed from ZIP+4 data that contains records of addresses, it does not contain ZIP+4 data that are associated with ZIP codes that exclusively serve Postal Office Boxes (PO Boxes). This enables a slightly more nuanced approach to allocating data between disparate geographies. By using an allocation method based on residential addresses rather than by area or by population, analysts can take into account not only the spatial distribution of population, but also the spatial distribution of residences. The latter feature is of particular interest to housing researchers because many of the phenomena that they study are based on housing unit or address. They originate directly from the USPS are updated quarterly, making them highly responsive to changes in ZIP code configurations and reflect the locations of both business and residential addresses. These unique files are derived from data in the quarterly USPS Vacancy Data. To provide additional avenues for merging these data, PD&R has released the HUD-USPS Crosswalk Files. While some acceptable methods of combining ZIP codes and Census geography exist, they have limitations. There are valuable data available only at the ZIP code level that, when combined with demographic data tabulated at various Census geography levels, could open up new avenues of exploration. One of the many challenges that social science researchers and practitioners face is the difficulty of relating United States Postal Service (USPS) ZIP codes to Census Bureau geographies. The HUD-USPS ZIP Code Crosswalk files between 2012 Q Q4 use the 2010 Census geographies whereas earlier files (2010 Q1 – 2011 Q4) use the 2000 Census geographies. The HUD-USPS ZIP Code Crosswalk files are now available for 2020 Census geographies beginning with the 2023 Q1 data release. Īugust 2022 Update: The HUD-USPS ZIP Code Crosswalk API now supports a new feature to get crosswalk data for a specific state or for all states for a specific quarter. To create an account and get an access token, please visit the API page here. With this API, developers can easily access and customize crosswalk data for use in existing applications or to create new applications. I have not purchased a single game on that account.HUD’s Office of Policy Development and Research (PD&R) is pleased to announce that HUD-USPS ZIP Code Crosswalk data are now available via an application programming interface (API). My alternate account that I use to idle games has 248 games owned. I've been doing this for a while now & my main Steam account has gone from around 850 games owned to over 1,100.

Step 1: Sign up for a free account on /join If you're using Windows 10 you can also use it's built in Mail app. A program or an App to instantly notify us when an email is waiting in our inbox, so we don't miss out on those games. My favorite program that I've been using for years is Howard Email Notifier. I don't know exactly how it works, but it will be responsible for sending us an email when someone posts about a free game on /r/FreeGameFindings.ģ. A website that will automate things for us. A Reddit page dedicated to free game findings from around the internet.Ģ. Are you one of those people, like me, that just love to hoard Steam games just because they're free? Well, here's an easy way to fulfill those hoarding habits.ġ.
