Craigslist personals are available in all cities that have a local Craigslist site; however, the number of ads available depends on the number of people who post in the city. As of 2015, Craigslist has more than 700 local sites in 70 countries.
Craigslist began as an email list of events sent out by Craig Newmark in 1995. The site now offers space to post ads covering a variety of topics, such as relationships, jobs, housing and local events. Some cities, such as San Francisco, have their own site, while others, such as the one located in the Upper Peninsula of Michigan, belong to one regional Craigslist site.
