Abstract In the last decade, the call for improved estimates of lesbians, gay men and bisexual (LGB) populations has grown steadily. This is related to the increasing visibility of same-sex unions and the rapidly evolving changes in the legal and normative institutional frameworks regarding same-sex relationships in Western countries. The aim of this article is to present the sampling strategy and discuss the quality of a recently conducted probability-based survey in the Netherlands that targeted mixed-sex and same-sex couples with and without children. The core questions addressed are (1) whether the sampling strategy paid off in terms of identifying same-sex households and (2) whether the collected sample is representative of the target population. While the sampling strategy has success in identifying same-sex households, the question of representativeness remains a challenging task in surveying LGB populations and couples in particular. Especially, aspects related to the sampling strategy, the survey mode and the covered topic of the research are central to understanding observed selection patterns in the examined mixed- and same-sex samples.

以概率方式调查同性关系中的人–荷兰的一个例子

摘要在过去的十年中，要求对女同性恋者，男同性恋者和双性恋（LGB）人口进行估计的需求稳步增长。这与同性工会的知名度不断提高以及西方国家有关同性关系的法律和规范性制度框架的迅速发展变化有关。本文的目的是介绍抽样策略，并讨论最近在荷兰进行的基于概率的调查的质量，该调查针对有子女和无子女的混血和同性伴侣。所解决的核心问题是：（1）抽样策略是否在确定同性家庭方面得到了回报；（2）收集的样本是否代表目标人群。虽然抽样策略已成功识别了同性家庭，在调查LGB人群尤其是夫妻时，代表性问题仍然是一项艰巨的任务。尤其是，与采样策略，调查模式和研究涵盖的主题有关的方面对于理解所检查的混合和同性样本中观察到的选择模式至关重要。
