Limitations on Popular Name Data

1. If we were to provide more than the top 1000 names, these names would be less popular and hence the number born in a particular year might be very small. We need to be sensitive to privacy issues, and so we can not include names with only a few occurrences. Thus we limit our national lists of names by sex and year of birth to the top 1000 names. Similarly, we limit our state lists to the top 100 names.
2. If we could expand our data to, say, the top 2000 or more names, the performance of our internet servers would degrade to the point where many people would be unable to access our our data. Even with our 1000 name limit, you may have experienced slow responses.

What percentage of all names are represented in the top 1000 names?
For U.S. births in 2007, the top 1000 names represent about 74 percent of all names.
