How many of me website has been one of the most popular websites to find out how many people share your name. It uses public data to estimate how many people share a given name or birthdate in the United States. Statistics gleaned from this website have been used in reaction image memes on Reddit.
HowManyOfMe is not working for some users, due to a DNS problem. This is a problem that occurs when web servers change or move to different hosts, and is generally not related to the website itself.
Another viable alternative to how many of me is Behind the Name, a website that delves into the etymology and history of diverse names. It also outlines the popularity of names in various regions.
