Facebook and Twitter, oh my! NEW County Profiles, and Data Updates


We've entered the world of social media - better late than never!

You can now get more information about our project, find out when our mapping team is out and about in the state, and learn about other cool food mapping projects by liking us on Facebook and following us on Twitter. Based on feedback from our survey, you indicated these were ways that you would like to get information. And social media allows us to share more info about projects and research outside of Maryland that is relevant to our work. Please join the conversation!

County Profiles

We have often been asked for quick statistics based on the data in the map. To date, we've only been able to pull these together on a case-by-case basis. Now we are making it easier to get statistics yourself! Downloadable from our website, these food and agriculture county profiles summarize all of the data layers in our map. They provide a quick reference guide, allow you to compare counties to each other, and give state totals and averages. We hope you find these useful! And as always, we welcome your feedback. These profiles are available in PDF versions for download from our "Special Projects" tab on our website. You may view them all in one file, or separately by county.

New Data Layers

  • Agriculture
    • Plant Hardiness Zones - Average annual extreme minimum temperatures are shown, which can be used in assessing what crops can be grown in different regions around the state.
    • Census of Agriculture Data
      • Government Payments - Total & Average Per Farm: Payments received from the federal government for agriculture, made directly to farm operators. These include key conservation programs such as: Conservation Reserve Program, Wetlands Reserve Program, Farmable Wetlands Program, and Conservation Reserve Enhancement Program; in addition to load deficiency payments, and other conservation and federal farm programs.
  • Food Retail
    • Food Access Data
      • USDA Low Income and Low Access Census Tracts - which show those areas found to be both low income and low access on the USDA's Food Access Research Atlas.
      • % Food Insecure - shows the percent of the population that is food insecure, as measured by the USDA that takes into account physical access to healthy food as well as sufficient income to afford healthy food.
  • Health
    • 2012 Obesity and Diabetes Rates - Prevalence rates have been updated to reflect the most recent data available
  • Demographics
    • Self Sufficiency Standard - Developed by the Center for Women's Welfare in 2012, the Self-Sufficiency Standard defines income necessary to meet basic needs (including taxes) without public subsidies (e.g., public housing, food stamps, Medicaid or child care) and without private/informal assistance (e.g., free babysitting by a relative or friend, food provided by churches or local food banks, or shared housing), taking into account family composition, ages of children, and geographic differences in costs. The data shown are for a family with 2 adults and 2 school age children.


All of these new data layers are defined in the "Glossary" in the "About the Map" section.
