I'm pretty new to ArcGIS Online and only have access to an AGO subscription so no ArcMap or Desktop. My question is this: I have an csv file with census tract numbers for a specific county (no addresses). How do I get the longitude and latitude data so that I can map in AOG? I'm assuming that I must join it to a dataset that has this information. How do I join it without ArcMap and Desktop? The idea is to eventually make a choropleth map or potentially a dot density map. Thank you for you assistance!
KML and Geodatabase versions: http://www.census.gov/geo/maps-data/data/tiger.html
I suggest looking here for shapefiles of census tracts: http://www.census.gov/cgi-bin/geo/shapefiles/index.php Geodatabases and KML files are also available.
I don't see a good way of creating a join with only ArcGIS Online.
