This is a fascinating examination of the history and development of a mundane fact of everyday life--addresses. We all have addresses; how else would we get our mail or tell people where we live?
Except we don’t all have addresses, and it's not just the homeless who lack them. In large parts of the world, including rural areas of the US, poorer and less privileged areas don't have street names and house numbers. That lack creates problems not just in telling potential visitors where you live, but in getting mail, applying for jobs, registering to vote, and qualifying for aid such as unemployment benefits. Or getting an ambulance to your house in an emergency.
