First, we looked at over 100 million publicly-available profiles on Facebook.   Next, we ran a rough tally on all the unique first and last names to get a general impression of popularity – we did not apply any intelligence to the data so nicknames like “Bob” and “Mike” were considered unique from “Robert” and “Michael.”

First Name Results
Here are the top 10 most popular first names on Facebook:

First Name                Count
1. John                   1,037,972
2. David                    966,439
3. Michael                798,212
4. Chris                     647,966
5. Mike                      535,065
6. Mark                     526,198
7. Paul                       511,504
8. Daniel                   504,203
9. James                    494,945
10. Maria                  484,693

Highlights:

• 9 of the top 10 most popular first names are male. This may be partially explained by the non-aggregation of nicknames since female names tend to have more variations.
• If nicknames were considered, Michael/Mike would probably be the most popular name.
• Most names are traditional American/English names even though most of the 167 million Facebook users crawled were not American.  “Mohammed,” one of the most common first names in the world, is not even in the top 100.

Last Name Results
Here are the top 10 most popular last names on Facebook:

Last Name                Count
1. Smith                1,049,158
2. Jones                   520,943
3. Johnson              440,978
4. Lee                        392,709
5. Brown                  375,444
6. Williams             372,486
7. Rodriguez          328,984
8. Garcia                  311,477
9. Gonzalez             277,987
10. Lopez                 269,896

Highlights:

• The last names list is more representative of Facebook’s global reach than first names.  Surnames like Lee, Rodriguez, and Gonzalez are not only popular in the U.S., but also all across the world.
• While some English last names like “Smith” prevail in popularity, they drop much faster than English first names.
• Compared to first names, last names drop off much faster in popularity: the 10th most common first name has 214,797 more occurrences than the 10th most common last name, and the 100th most common first name has 101,065 more occurrences than the 100th most common last name.  This is not as surprising since last names are naturally “collective buckets” for first names.

Full Name Results
Here are the top 10 full names on Facebook:

Full Name                    Count
1. John Smith             75,980
2. Joe Smith                14,648
3. Bob Smith               13,846
4. Mike Smith            11,199
5. Juan Carlos            10,254
6. Jane Smith             10,023
7. Mike Jones             10,014
8. David Smith            9,322
9. Sarah Smith             8,534
10. James Smith          8,397

Highlights:

• These names, especially the “John Smith,” are common ones that many of us have come across before.  What is more difficult to ascertain is how many of these names actually correspond to a real person instead of a false user account.
• The one non-obvious surprise is “Jane Smith.”   “Jane” doesn’t appear in the top 100 names and is not a popular name for women under 30.  This fact, combined with “Jane Smith” being a name people would make up, leads us to suspect that a big portion of those Janes on Facebook correspond to fake accounts.

Takeaways
In general, results of the study suggest that Facebook users have predominantly American and English names.  This is particularly true with first names and full names.  Given Facebook’s birth in the U.S. and quick adoption among college campuses, the popularity of American and English names are not entirely surprising.  Additionally, it is not uncommon for users in foreign countries to go by American names.

More indicative of Facebook’s global presence is the variation in last names and how the most-popular surnames will change as the social network continues to grow internationally.
