Data and Statistics

Learn how to access data and statistics on a variety of topics.

Data Requests via the Data Fund

The Data Fund provides JHU researchers the opportunity to make requests for known datasets that are not readily accessible via the library data subscriptions. Each year, the library is able to provide a small amount of funding to a select number of researchers to facilitate their use of secondary data.

If you have a specific need for secondary proprietary data without security or access restrictions that cannot be obtained by other means please submit a request using the form below for consideration.

Data Fund Purchase Request Form

Please note that submission of the form is not a guarantee of funding. Applicants will receive communication from the data and statistics consultant who will work with the researcher and the academic liaisons within the researcher's discipline to discuss the next steps for the potential use of Data Fund resources to gain access to secondary data. (Undergraduate researchers must have the endorsement of a faculty member to apply. While funds may be made available for undergraduate research projects in special circumstances, the fund's primary mission is to fund data for faculty and graduate student research.)

Local Resources

Vital Signs
A Baltimore Neighborhood Indicators Alliance (BNIA) publication that shows neighborhood change over time in areas of education, child and family well-being, health, housing and development, sanitation, transit, neighborhood action, and workforce and economic development.

Open Baltimore
A tool from Baltimore City that provides open access to crime, property taxes, and various city polygon layers. This tool provides visualization tools as well as download capabilities.

Census Geography for Baltimore and Maryland

When requesting data specific to Baltimore neighborhoods (Hampden, Charles Village, Mt. Vernon, East Baltimore, etc.), it is important to note that neighborhood level data from the Census is not readily available.

There are 11 levels of geography for the state of Maryland:

  • Metropolitan and Micropolitan Statistical Areas,
  • Counties,
  • County Subdivisions
  • Places,
  • Census Tracts,
  • Block Groups,
  • Blocks,
  • Congressional Districts,
  • School Districts,
  • State Legislative Districts,
  • Zip Code Tabulation Areas.

Data is not necessarily available for all Census data products for all of these levels.

Before starting work with Census data or beginning to work with mapping tools such as ArcGIS, it is important to have a basic understanding of Census geography.

The Baltimore Neighborhood Indicators Alliance (BNIA) has developed a method to create Baltimore Community Statistical Areas (BCSAs) that have the stability to track changes in city conditions and demographics over time. These BCSAs comprise more than one neighborhood.

GIS Resources

Access to ArcGIS

Current Johns Hopkins faculty and students can obtain a free copy of ArcGIS from the GIS and Data Services Deparment on A-level for one year of student use or to install on a JHU-owned machine. Both are solely for research purposes. Please see the GIS Guide for more information.

We do have ArcGIS Business Analyst accessible on all public machines in the GIS and Data Services area. Current data for Maryland Property View is accessible online and historical data is available on DVD for use within the library.

Population and Geospatial Information

Baltimore Neighborhood Indicators Alliance - Jacob France Institute (BNIA-JFI)
The BNIA-JFI is a valuable local data resource based at the University of Baltimore.  Here you can view aggregate information at the neighborhood-level on a variety of topics. If what you find online is not sufficient for your research or teaching, they will take some special requests for thematic maps or data files. See the map gallery for thematic maps and links to other boundary maps that could help you with your spatial analysis. You can download both tabular and geospatial data files from BNIA.

EASI Market Planner (via Conquest/DataPlanet Statistical Datasets)
You can get consumer behavior, expenditures, media use, and much more down to the tract level.  You can export the data as an Excel, SAS or even GIS Shapefile.

Maryland State Data Center (MDSDC)
The MDSDC is an official partner with the U.S. Census Bureau and is based within the Maryland Department of Planning.  From the MSDC you can download data on population estimates, projections and both PDF maps and shapefiles (zip code level street maps) for MD, its counties, cities, and smaller geographies.

SimplyAnalytics
SimplyAnalytics is an online geospatial data product that allows the novice user to quickly create thematic maps and reports using extensive demographic, business and marketing data.  You can analyze data down to the block group. Knowledge of ArcGIS is NOT required.  If you would like to save your work, it is recommended that you create an account separate from your JHED (otherwise choose guest).  Please note that we currently only allow 5 concurrent users.  You are able to download tabular reports and shapefiles.

Social Explorer
This resource is the best resource for downloading the latest (and historic) Census data (Decennial and American Community Survey) at the Baltimore tract/block group (or other small geography) for in-depth analyses with both ArcGIS and statistical packages. Use the online interface to create your table and then download in the format of your choosing (note the .csv format with DBF friendly column labels is best for ArcGIS or for packages not already represented in the interface).  TIP: When opening your .csv file, double click on the top left corner of the table - the corner between A and 1- in order to expand columns to the correct size).  Do NOT forget to download your Data Dictionary as well.

Statistics from Local Agencies

Baltimore City Health Department
A wealth of statistical information about the state of Baltimoreans' health.

Maryland Behavioral Risk Factor Surveillance System (BRFSS)
Ongoing telephone surveillance program designed to collect data on the behaviors and conditions that place Marylanders at risk for chronic diseases, injuries, and preventable infectious diseases. The data collected are used to characterize health behaviors, ascertain the prevalence of risk factors, and target demographic groups with increased needs.

Maryland Domestic Violence Statistics
The Maryland Network Against Domestic Violence (MNADV) has been working since 1980 to eliminate domestic violence in Maryland through education, training, and advocacy.

Maryland Report Card
A collection of data compiled on an annual basis to provide information on school performance to all education stakeholders; provide information to support school improvement efforts; and to provide accountability at the state, school system and school level or reporting educational progress.

Office of Workforce Information and Performance of the Maryland Department of Labor provides up-to-date information on the Maryland Labor force including current employment and unemployment rates, the job market, listings of major employers, commuting patterns and wage data.
