<p>This dataset contains the locations of all properties that have been sold by the Detroit Land Bank Authority through a direct sale to a purchaser (rather than through their side lot or home auction programs). While most housing transactions fall into one of those two categories, a small number have been sold through other programs and means. Information contained in this dataset includes name of purchaser, date of transaction, and the cost the purchaser paid for the property. <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/DLBA_ProgramSales/Metadata_DLBADirectSales.xls" target="_blank">Field description metadata are available for download</a> to provide more detail on the specific contents of the dataset.</p> <p>The analyst downloaded these data in their raw format from the City of Detroit's Open Data Portal on March 31, 2015. The analyst then geocoded the data to spatialize the properties and assign a parcel ID to each record.</p>

updated 16 days ago.
In 2009, Data Driven Detroit partnered with Living Cities, the Detroit Office of Foreclosure Prevention and Response and Community Legal Resources (Michigan Community Resources) to conduct a survey of 1-4 unit residential structures and vacant lots in the City of Detroit. Surveyors went out in the field in August and September of 2009, and following this, data were entered into a database and cleaned. The survey collected information on property type, condition, vacancy, danger to the surrounding community, fire damage, and improvements on vacant lots.For more information on the DRPS, including aggregations and maps of the original data, please visit www.detroitparcelsurvey.org.<div><br /></div><div>Upon request, field description metadata is also available for this dataset.</div>

updated 16 days ago.
<p>In January, 2014, Data Driven Detroit (D3) purchased a license of the Valassis Corporation's VNEF Plus database to receive quarterly updates of address-level vacancy data. Though the address-level data are restricted by confidentiality clauses, D3 processed and aggregated this database to the Census block-level to provide high-resolution tracking of structure vacancy in Detroit across time. The dataset contains data on the number and percent of vacant structures (with whether a parcel contains a structure identified by Motor City Mapping survey data) in each of the nearly 16,000 Census blocks in Detroit. The data span the timeframe from Q4 2013 through Q4 2014.</p> <p><a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/QuarterlyVacancy_BlockLevel/Metadata_BlockLevel_VacancyAggregations.xls" target="_blank">Field description metadata</a> and a <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/QuarterlyVacancy_BlockLevel/Narrative_BlockLevel_VacancyAggregations_Final.pdf" target="_blank">narrative summary</a> providing further detail on the creation of the dataset are also available for download.</p>

Archival Tax Foreclosures in Detroit, 2002 - 2013
(from Property Information)
Shared by

updated almost 3 years ago.
<p>Wayne County follows a relatively fixed process for initiating tax foreclosures. The county serves notice to any parcel that is more than three years delinquent on property tax payments, and these properties are then sold to the highest bidder in two auctions - one in early September, and one in October. While there have been some exceptions to this schedule (a June 2012 auction of unsold foremost among them), properties listed in the September tax auction represent a strong proxy for identifying the universe of tax-foreclosed properties.</p> <p>This file identifies parcels within the City of Detroit that were listed in the September Wayne County tax foreclosure auction in any year from 2002 through 2013. It contains information on year of foreclosure, as well as the total number of times that a property has been subject to tax foreclosure. The work to produce this dataset was conducted in September 2013, and the data were subsequently integrated into the Motor City Mapping project.</p> <p>The purpose of this file is to help provide information on how Detroit's tax foreclosure crisis has developed over time, enabling community members and decision-makers to make more informed decisions when developing strategies to combat this growing problem.</p> <p>Metadata associated with this file includes <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/WCT_TaxForeclosures/ArchivalTaxForeclosure_Metadata_Final_12152014.xls" target="_blank">field description metadata</a> and a <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/WCT_TaxForeclosures/ArchivalTaxForeclosures_Documentation_12152014_Final.pdf" target="_blank">narrative summary</a> detailing the creation of the dataset.

Vacancy Index, November 2014 (Aggregated)
(from Data Driven Detroit Data Portal)
Shared by

updated 16 days ago.
<div> <p>The D3 vacancy index was designed to provide a more nuanced assessment of structural vacancy than the "occupied/unoccupied/maybe" categories used in the Motor City Mapping windshield survey. The dataset includes several sources, including Motor City Mapping, utility data, and other resources to create a score evaluating the occupancy status of a parcel. These values are then coded as "Likely Occupied", "Potentially Vacant", "Likely Vacant", and "Very Likely Vacant", helping to show a spectrum of vacancy across Detroit.</p> <p>Because the vacancy index incorporates proprietary data sources, D3 is unable to release the raw values of the index to the public at the address level. To allow the public to obtain some of the benefit from this highly-effective tool, however, D3 aggregated this data to the Census Tract level. This file allows Detroit's policymakers and community members to track vacancy across the city using data that is as up-to-date as possible.</p><p>Metadata associated with this file includes <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/Vacancy_Index_Aggregation/Metadata_VacancyIndexAggregation.xls" target="_blank">field description metadata</a> and a <a href="http://datadrivendetroit.org/web_ftp/motorcitymapping/Metadata/Vacancy_Index_Aggregation/VacancyCount_Aggregated_Documentation_Final_12302014.pdf" target="_blank">narrative summary</a> documenting the creation of the dataset.</p></div>
