HealthyCity.org currently offers users access to over 120 demographic and community characteric variables, from 9 different data sources. Our data and sources are described in detail at: http://www.healthycity.org/c/help/sc/indicator. For the proposed national service, some of the California-specific data sources may not be available nationally (such as data from the California Health Interview Survey or from the WIC program), but their functions may be replaced by other data sets. There are a number of health and economic data that state and federal offices use that are only available at the county level (so they cannot be displayed on our current site); offering a national view will make comparisons and disparities between counties and states accessible to users. Users will be able to:- Upload their own data sets- Overlay data points on top of demographic and other data- Map and analyze data within a radius around an address, or within a ZIP code, city, legislative districts or other jurisdictions- View core demographic and other data for the selected geography in tables and charts- View assets, such as schools, parks, fire and police stations, on an interactive map, with types of service (identified by icons)- Identify information about assets or service providers by scrolling over their icons- Cut and analyze data by over 60 demographic, health and other indicators
