You posted this in the Census Records section. The most recent U.S. census available to the public is the 1950 one. There are online sites that have name indexes for censuses. If you have a common surname, you must have some other information to narrow your search, such as spouse, children, occupation, etc. Without you providing any more information, you are going to get generic responses such as this one.
If you are looking for a particular person on a Census Record, you need only the name and the state where the person lived to get started. The US Census has been taken every ten years since 1790, and the 1950 Census is the most recent available one. You can find more about the Census on this page linked here.
To start researching in the Census, you can use the web page Search Census Records Online and Other Resources, which provides information about accessing these records online. There may be a fee for using Ancestry. Please check for access at your local library as many library systems subscribe to these sites, making them free for their patrons. FamilySearch can be accessed with a free account.
