Government documents can be created at the city, town, county, state, provincial, federal, or national level. These documents include a variety of information such as demographics, policies, laws, and reports, to name a few. Contrary to popular belief, these documents are not all on the internet though many are. You may have to go to a particular agency or request that they send you the information you are looking for.
When you are looking for government documents, one place is the official website of a government municipality or organization. From there, you may be able to access reports or data or at least get a contact name for further assistance.
