Abstract：
Random digit dial surveys with mobile phones risk under-representation of women. To address this, we compare the characteristics of women recruited directly with those of women recruited through referrals from male household members. The referral process improves representation of vulnerable groups, such as young women, the asset poor, and those living in areas with low connectivity. Among mobile phone users, we show a referral (rather than a direct dial) protocol includes more nationally representative proportions of women with these attributes. While seeking intra-household referrals may improve representation, we show that it does so at a higher cost.
摘要：
使用手机进行随机数字拨号调查，女性代表性不足。为了解决这个问题，我们比较了直接招募的女性和通过男性家庭成员转介招募的女性的特征。转介过程提高了弱势群体的代表性，比如年轻女性，资产贫乏，以及那些生活在低连通性地区的人。在手机用户中，我们显示转诊(而非直拨)方案包括具有这些特征的更具全国代表性的女性比例.虽然寻求家庭内部转介可能会提高代表性，我们证明它的成本更高。
