To search for people on Facebook that reside only in the United Kingdom, the easiest method of search is to put their name in Facebook's search bar along with the parameters "United Kingdom" or their country of residence, such as "Ireland." If a person's more precise location is known, a people search can be conducted through Facebook as well.
To perform a people search in Facebook, a user would need to visit the Find Friends page while logged into Facebook. From there, a person can filter the search by hometown, city, school and other parameters. To search for a person in the United Kingdom using this method, a more precise area would need to be known, as in John Smith, Liverpool, England.
