Surnames / Family names data

 

---

 

This data table, built  by GRC Data Intelligence, has been created by processing real world data files and counting the occurrences of each surname/family name.  As names can be very diverse, the file has been cleaned to exclude obvious errors and names containing initials, given names or additions such as seniority indicators (Sr, Jr. etc.);  but as it has been created from real world data it may contain real world errors.  To reduce errors, only those names found five or more times in real world data files are released.  For the 2011-3-1 release, the file contains 482739 records, created from analysing over 37.3 million data records from over 410 sources.  

 

The data contains:

 

	Unique record number
	Country information (ISO 3166 codes).  This applies to the country in which the name was found, not where the name originated.
	The string as found.  Names are very diverse and during cleaning strings are assumed correct unless clearly incorrect.
	A corrected name.  Corrections are only made when there is a clear indication that a name is incorrect and the correct version is obvious.  Thus is is never correct to assume that Smyth should be Smith. However, Andr� can clearly be corrected to André.
	A count to show the number of times this surname/family name has been found in real world data.  The higher this number, the more likely that the string is a name.  Only strings found 5 or more times are released in this file.

 

The table attempts to capture what is found in the real world and to lend itself to processing according to most uses.  Each record is unique by country and name as written (including casing).  You can therefore expect to find each name multiple times within the file in this way:

 

Country	Name	Count
GB	SMITH	5231
GB	Smith	7563
GB	smith	17
GB	JONES	3876
GB	Jones	6252
GB	jones	5

 

Coverage figures are here.

 

Strings which are known not to be surnames/family names, or which are or include given names, or which contain additional information such as forms of addresses or seniority indicators, are excluded from the release file.
