First step is to know more about your community. What's the average income in your community? How many children under 5?
Looking for how many existing business there are in the area? The official count is done by the Census Bureau's County Business Patterns. But the latest compilation is 2016, and it's only down to the county level. I'd supplement with Google searches and news articles.
Local news articles are your best bet for a more subjective take on what's going on in your community.
Easy way to get a sense of news articles is to do a Google search, then limit to News.
