<p>Count of family names (surnames, last names) in Peru, from an approximately 7% sample of the adult population.</p> <p>In Peru, many people are registered as supporters of political parties, and their names are published by the&nbsp;<a href="https://aplicaciones007.jne.gob.pe/srop_publico/Consulta/PadronAfiliado">Registro de Organizaciones Pol&iacute;ticas</a>.&nbsp; The lists include a DNI (national identity number) for each person to avoid duplicates. The 1,572,002 people on these lists (excluding the regional movements) represent around 7% of the adult population of Peru.</p> <p>Their maternal and paternal family names&nbsp;have been sorted and counted. Nearly all of the names have entries for both paternal and maternal names.</p> <p>These 3,142,561&nbsp;family names represent 85,395 different names, most of which are infrequent.&nbsp; The file has been limited to&nbsp;names that occur&nbsp;ten or more times in the sample, which is 12,139&nbsp;unique names (3,021,655 names, more than 96% of the total).</p> <p>Each row in the file contains the rank, a percentage of that name in the entire set of 3,142,561 names, a count of the times the name occurs in the sample, and the name.&nbsp;</p> <p>There are some names (around 800) in this&nbsp;file&nbsp;that contain a space. In most cases, these are names like &quot;GARCIA DE RUIZ&quot;, where RUIZ is the name of the woman&#39;s husband.&nbsp; There are also cases where the name is like &quot;DE LA CRUZ&quot;, which is a complete family name.&nbsp; No attempt has been made to remove&nbsp;the part of names which refer to the husband&#39;s name, this could be considered for a later version.&nbsp;&nbsp;&nbsp;</p> <p>&nbsp;</p>
