NEARBY COLLEGE & UNIVERSITY LIBRARIES
Many colleges and universities (especially ones that are publicly-funded) offer some access to their collections if you are able to visit.
GOVERNMENT & ORGANIZATIONAL WEBSITES
Your federal, state, and local governments gather immense amounts of data about a number of things: population, economy, etc. Similarly, a number of organizations have established reputations for being trusted information sources. You can find these websites via a Google search and you can even make Google search for them specifically (site:.gov or site:.org after your search terms).
However -- and it's a big however -- please think critically about any source that you find, especially via the open web. Is its information factual? Cited? Who's creating it and why? Is there any bias present? Information left out? Is it up-to-date? Why should you trust and include this source over others?
