Landgrid has integrated a powerful nationwide vacancy dataset from the United States Postal Service. To access this amazing data on our platform & to conduct surveys with the app, sign up or upgrade to Landgrid Pro for just $10/month or $100/year. For multiple users, downloading USPS data in a CSV format, additional functionality, custom integrations/imports & for dedicated support, check out Landgrid Enterprise or contact us at firstname.lastname@example.org.
This dataset indicates when a building of any zoning type is not receiving mail. It is the perfect out-of-the-box dataset to start understanding vacancy in your community.
To show data on the map using your Pro or Enterprise account, just do the following:
1. Navigate to the "Filter" function on the map UI
2. Go to "USPS Vacancy" and select "Y"
3. Do the same with "USPS Residential" field.
4. Then click "Load on Map" & see those vacant & residential parcels light up the map along with the count of parcels for the matching query within any boundary - county, city, neighborhood, zipcode & census!
5. Press save & give your project a name in order to be able to quickly return to this vacancy view.
You can do the same & color code your maps for vacancy data using the "Style" function on the map UI!
You now already have the vacant properties highlighted & saved to your project. Use this data to survey vacant properties next. This makes your & your canvassers' job easy & focused.
To start a survey of vacant properties, follow these quick steps:
1. Select "Survey" on the left hand panel of the map UI on the Landgrid Mapping Platform.
2. Use our "Survey Editor" to spin up a survey questionnaire in a matter of minutes.
3. Your survey will appear in the Landgrid App on your phone or tablet.
4. You can then start visiting properties to take pictures & notes on those vacant properties, which will automatically get loaded onto your map.
We're excited to provide you USPS vacancy data nationwide at the parcel level, something that to our knowledge has not been done before. While aggregated USPS vacancy data is a widely-accepted indicator and has been used in academic studies and research since at least 2010, there has rarely been a way to crack that data open and see how those aggregations have been made, or how reliable the data is.
While we know that the data is not perfect - and we hope that you get in touch with us to share your findings, so we can refine this dataset going forward - the Loveland team feels that this is an important tool for our friends and partners to have, and a revolutionary step forward in understanding the property dynamics in our communities. Happy Mapping!!!
All things you need to know about the USPS Residential & Vacancy data, now available as part of our dataset & platform:
The United States Postal Service maintains a database of every deliverable address in the US.
This data is collected and maintained by their letter carriers.
As part of their regular processes, letter carriers identify addresses as either primarily residential or non-residential delivery points. That information is recorded as what the USPS calls their "Residential Delivery Indicator" (RDI).
There are times when the letter carriers record addresses that are valid addresses, but for some reason are not currently collecting their mail. This is recorded as a their "Vacant Flag". It is important to understand these addresses could receive mail, but are not currently receiving mail. This is different from addresses that are not considered valid for receiving mail, which are addresses that might be assigned to new developments where buildings have not been built or are not yet occupied.
~89 million parcels currently have USPS data attached.
We have ~117 million addresses in our dataset and we have matched approximately 89 million of those addresses for a total match rate of 76%.
As this is our initial pass over the parcel addresses in our dataset, we expect to increase this number on subsequent passes over our dataset.
Additionally, counties typically only maintain 1 address per parcel and a significant percentage of those parcel addresses are non-deliverable parcels like farm fields or other vacant lands.
USPS data will be updated approximately every 2 months as and when it is released by the USPS Certified Data Vendor we work with.
