This study examined errors in estimating household gun ownership that result from interviewing only 1 adult per household.
Data from 2 recent telephone surveys and a series of in-person surveys were used to compare reports of household gun ownership by husbands and wives.
In the telephone surveys, the rate of household gun ownership reported by husbands exceeded wives' reports by an average of 12 percentage points; husbands' reports also implied 43.3 million more guns. The median "gender gap" in recent in-person surveys is 7 percentage points.
Future research should focus on respondents' reports about personally owned guns.
本研究调查了因每户仅采访一名成年人而导致的家庭枪支拥有量估计错误。
使用来自两项近期电话调查和一系列面对面调查的数据,比较丈夫和妻子报告的家庭枪支拥有情况。
在电话调查中,丈夫报告的家庭枪支拥有率平均比妻子的报告高出12个百分点;丈夫的报告还显示枪支数量多出4330万支。近期面对面调查中的“性别差距”中位数为7个百分点。
未来的研究应关注受访者关于个人拥有枪支的报告。
