Published description

本卡聚焦附件所列 2024 ACS 1-Year PUMS 查询：get=SEX,PWGTP,MAR 并以 SCHL=24 筛选。页面还列出 Puerto Rico PUMS 及其他年度和数据集的文档入口，不能把这些入口视为本次已读取的数据或完整变量契约。

Inputs

  • get：附件示例列出 SEX、PWGTP、MAR 字段代码。
  • SCHL：附件示例筛选值为24；本页未解释该值含义，不补造编码解释。
  • key：个人 API key，原文明示所有数据查询均需要。

Outputs

  • 页面给出数据查询示例，但未展示查询响应体或完整 schema。
  • 每个所列数据集另有 variables 的 HTML、XML、JSON 元数据链接；这些格式不能直接当作该查询结果 schema 的证明。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

  • 必须使用 key 的声明适用于原文所述所有数据查询；不能将旧的匿名访问假设沿用到当前附件。
  • 年度、数据集及 Puerto Rico 路径各不相同；不能将一个示例推广为任意微观数据集的完整契约。
  • 本页没有给出数值限流、配额、价格、SLA 或完整查询响应格式。
  • 未申请 key、调用 API、读取人口微观记录或验证输出。

Unknowns

  • 数据查询的完整响应 schema、变量代码含义与地理限制尚未由本附件独立确证。
  • 费用、限流、配额、SLA、日志保留和当前服务可用性未知。

Add a public correction or observation

Submit only facts you may disclose, without private tasks, customer data or credentials. Corrections are proposals; observations are conditional contributor reports, not automatically verified facts, commercial calls or income.

Propose a sourced summary correction

This form proposes a summary change for the current fixed version. Other supported fields use the original API. Concurrent version changes return a conflict.
