SNAP Policy Data Sets

The SNAP Policy Database provides a central data source for information on State policy options in the Supplemental Nutrition Assistance Program (SNAP). The database includes information on State-level SNAP policies relating to eligibility criteria, recertification and reporting requirements, benefit issuance methods, availability of online applications, use of biometric technology (such as fingerprinting), and coordination with other low-income assistance programs. Data are provided for all 50 States and the District of Columbia for each month from January 1996 through December 2011.

The information in this database can facilitate research on factors that influence SNAP participation and on SNAP's effects on a variety of outcomes, such as health and dietary intake. More specifically, the database can be used to:

- Describe the differences in the State-level administration of SNAP and trends in the adoption of specific State-level SNAP policies,
- Examine how State policies affect household-level participation in SNAP, and
- Estimate the effect of SNAP participation on outcomes such as health and food spending by combining this data with nationally representative survey data. The SNAP Policy Database provides a potentially exogenous source of variation in program participation and can be used in instrumental variables estimation techniques.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

SNAP政策数据库提供了一个关于补充营养援助计划（SNAP）州级政策选择的信息中心数据源。该数据库包含了与资格标准、再认证和报告要求、福利发放方式、在线申请的可用性、生物识别技术（如指纹识别）的使用以及与其他低收入援助计划的协调相关的州级SNAP政策信息。数据涵盖了从1996年1月至2011年12月每个月份的所有50个州和哥伦比亚特区的数据。数据库中的信息有助于研究影响SNAP参与的因素以及SNAP对各种结果（如健康和饮食摄入）的影响。具体而言，该数据库可用于以下目的：
- 描述州级SNAP管理的差异和特定州级SNAP政策的采用趋势；
- 考察州政策如何影响家庭层面的SNAP参与；
- 通过结合本数据与全国代表性调查数据，估计SNAP参与对健康和食品支出等结果的影响。SNAP政策数据库提供了参与该项目的潜在外生变量来源，可用于工具变量估计技术。本记录来源于为https://data.gov目录提供数据的USDA企业数据目录。本记录的数据包括以下资源：SNAP政策数据集。欲获取完整信息，请访问https://data.gov。
