The ArcGIS ecosystem contains thousands of data layers, many of which can be used alongside your own data to enhance analysis and visualization. In this tutorial, you\u2019ll search for data using authoritative layers that have been shared in ArcGIS Online.\r\n\r\nIn many cities, a shortage of affordable housing is driving up costs. In this tutorial, you are an analyst studying housing access in Boston, Massachusetts, and you need to find data on affordable housing. You\u2019ll start by exploring data from American Community Survey (ACS). Then you\u2019ll filter the data and customize your map to only show data for your community.\r\n<h3><strong>Browse Data from ArcGIS Living Atlas of the World<\/strong><\/h3>\r\nThe first step in a GIS project is deciding what data to use. Authoritative data and different types of layers shared by the GIS community are accessible in ArcGIS Online through your map, so you can explore them in one place.\r\n\r\nTo find data on housing affordability, you\u2019ll start your search using ArcGIS Living Atlas of the World, a curated collection of geographic information from authoritative sources.\r\n\r\n1.
