Data for: Singles of Both Sexes Expedite Reproduction: Shifts in Sexual-Timing Strategies Before and After The Typical Age of Female Menopause

The Excel sheet is divided into 3 tabs, reflecting the three different waves of Singles in America used in this work and all raw variables needed to draw identical results described in our paper. This dataset does not include transformations (e.g. Stress remains in categorical, not numeric, form). Singles in America is sponsored by the online dating company Match.com; however, participants were not drawn from the Match.com or subsidiary site populations. Additional details on how each sample was collected are available in the manuscript.

This dataset contains only a subset of the original Singles in America dataset, both in terms of individuals included and variables measured. The original data in Study 1 and 2A limited participation to US residents age 21+ identifying their sex as male and female. Further, those individuals were only included if they were not married, engaged, in a domestic partnership, or living together. The sample provided here is further limited to heterosexuals who were not currently dating someone and also excludes those not providing their marital status. Study 2B recruited individuals as young as 18 who were single in the legal sense (i.e. being unmarried). The sample shown here includes only heterosexuals identifying as male or female who were not in a commited dating relationship and were either single and not seeing anyone or casually dating one or more people.

Data Provided (Varying by Study):
Age: In Years
Sex: Male or Female
Sexual-Timing Strategy: "How long do you typically wait before having sex with a new partner?". Blanks in Study 2B reflect individuals who preferred not to answer or did not give a response.
Sexual Thoughts Frequency: How often participants thought about sex.
Sexual Activity Frequency: How often participants had sex in the past 12 months.
Stress Over Biological Clock: Stress produced by ticking of biological clock on a 5-point Likert-type scale.
Comments on Single Status A Month: 0-19, with individuals replying '20+' having their response removed.

该 Excel 表格分为三个标签页，分别反映了本工作中使用的“美国单身人士”三个不同波次的调查数据，以及为了重现论文中描述的相同结果所需的全部原始变量。本数据集未包含任何转换（例如，压力值保持为分类形式，而非数值形式）。“美国单身人士”项目由在线约会公司 Match.com 赞助；然而，参与者并非来自 Match.com 或其子公司网站的用户群体。关于如何收集每个样本的详细信息，可在论文中找到。本数据集仅包含“美国单身人士”原始数据集的部分内容，既包括个体样本，也包括测量的变量。在研究 1 和 2A 中，原始数据仅限于年龄在 21 岁以上，并自认为是男性或女性的美国居民。此外，只有未婚、订婚、处于家庭伴侣关系或同居状态的个人才会被包括在内。此处提供的样本进一步限定为目前未处于恋爱关系中的异性恋者，并排除了未提供婚姻状况的个人。研究 2B 招募了年龄至少为 18 岁的单身人士。此处展示的样本仅包括自认为是男性或女性的异性恋者，他们未处于承诺的恋爱关系中，且要么单身未与任何人交往，要么与一人或多人在约会。提供的数据（根据研究不同而有所变化）：年龄（以年为单位）、性别（男性或女性）、性时机策略（“你通常多久与新的伴侣发生性关系？”）、性思维频率（参与者思考性事的频率）、性活动频率（过去 12 个月内性交的频率）、对生物钟压力的感知（在 5 点李克特量表上的压力感知）、关于单身状态的评论（0-19，回复“20+”的个人将被移除）。
