收藏资源简介：
Datamata 技能需求指数数据集是一个每日更新的技术劳动力市场分析数据集，用于追踪数据、工程、产品、DevOps、安全和人工智能六大角色类别中各项技能的需求动态。数据集基于每日从公共申请人跟踪系统（如Greenhouse、Lever、Ashby）和聚合招聘板抓取的活跃技术职位列表构建，通过计算提及特定技能的职位列表占总活跃列表的百分比来量化技能需求份额。该数据集包含551行数据（截至2026年6月25日最新快照），每行代表一个特定日期、类别和技能的组合。核心字段包括：快照日期（snapshot_date）、角色类别（category）、标准化技能名称（skill）、技能所属族系（skill_group）、提及该技能的活跃职位数量（listing_count）、该类别当日总活跃职位数量（total_listings）、技能需求百分比（demand_pct，计算为listing_count/total_listings×100并四舍五入至0.1），以及将该技能列为硬性要求的职位数量（required_count，早期快照可能为空）。数据集适用于分析技术技能的市场需求趋势，识别各领域中最受追捧的技能，区分硬性要求与优先考虑的技能，并通过追加每日快照来追踪技能需求份额随时间的变化。数据以CSV格式提供，采用CC BY 4.0许可证，允许在注明出处的情况下自由使用和改编，包括商业用途。
The Datamata Skill Demand Index dataset is a daily updated technical labor market analysis dataset used to track the demand dynamics of various skills across six role categories: data, engineering, product, DevOps, security, and artificial intelligence. The dataset is constructed based on daily active technical job listings scraped from public applicant tracking systems (such as Greenhouse, Lever, Ashby) and aggregated job boards, quantifying skill demand share by calculating the percentage of active listings that mention specific skills out of the total active listings. The dataset contains 551 rows of data (latest snapshot as of June 25, 2026), with each row representing a combination of a specific date, category, and skill. Core fields include: snapshot date (snapshot_date), role category (category), standardized skill name (skill), skill group (skill_group), number of active job listings mentioning the skill (listing_count), total active job listings for that category on the day (total_listings), skill demand percentage (demand_pct, calculated as listing_count/total_listings×100 and rounded to 0.1), and the number of job listings that list the skill as a hard requirement (required_count, which may be empty in early snapshots). The dataset is suitable for analyzing market demand trends for technical skills, identifying the most sought-after skills in various fields, distinguishing between hard requirements and preferred skills, and tracking changes in skill demand share over time by adding daily snapshots. The data is provided in CSV format under the CC BY 4.0 license, allowing free use and adaptation, including commercial purposes, with attribution.
