The novel coronavirus disease 2019 (COVID-19) is impacting families on an unprecedented scale across the state of Indiana. According to the US Bureau of Labor Statistics, the state's unemployment rate for May climbed to 16.9 percent, which is the highest number ever recorded in Indiana. Lost or reduced wages have resulted in significant food insecurity, and several resources that residents normally would depend on have become unavailable during the COVID-19 pandemic. Food banks are being stretched to their limit. School closures have changed access to free and reduced-cost breakfasts and lunches for students. Food staples normally available at grocery stores have become scarce.In response to the quickly spreading outbreak, the state of Indiana turned to the Geographic Information Office (GIO), within the Indiana Office of Technology, to fast-track the new, mobile-friendly Food Assistance Availability Map._Communities around the world are taking strides in mitigating the threat that COVID-19 (coronavirus) poses.

Please cite the Census and ACS when using this data.Data Note from the Census:Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see Accuracy of the Data). The effect of nonsampling error is not represented in these tables.Data Processing Notes:This layer is updated automatically when the most current vintage of ACS data is released each year, usually in December.
