Brazilian First Names and Gender Ratios

This dataset contains a list of ~74,000 Brazilian first names and how often each each name is used for a male or female candidates in the 2000, 2004, 2008, and 2012 municipal elections in Brazil. Thus it effectively works as a tool to classify the gender of any Brazilian (and perhaps Portuguese) name.The original data can be found on the Brazilian Electoral Tribunal's website here. In total, there are 1,653,604 candidates in municipal elections from 2000-2012 and 1,652,685 had gender reported in the officially provided data. I simply take the first characters in the reported names that preceded a space and count the reported genders associated with that name. This yielded 74,650 unique first names which make up this dataset. There are errors in this data set, but if you are matching from a well-formed list of names than this should work fairly well as a prediction of the gender of the names in a different list with minimal manipulation of the original dataset.本数据集收录了约74000个巴西人名，以及2000、2004、2008、2012年巴西市政选举中，各姓名分别用于男性与女性候选人的频次统计数据。因此该数据集可作为分类巴西（乃至葡萄牙语）姓名性别归属的有效工具。相关原始数据可于巴西选举法庭（Brazilian Electoral Tribunal）官网获取。2000至2012年间巴西市政选举共有1653604名候选人，官方公布数据中1652685名候选人标注了性别信息。笔者仅提取官方公布姓名中空格前的完整部分作为名字，并统计与该名字关联的性别标注情况，最终得到74650个唯一的人名，构成本数据集。本数据集存在一定误差，但如果待匹配的姓名列表格式规范，仅需对原始数据集进行极少量处理，即可较为准确地预测其他姓名列表中对应姓名的性别归属。
