The Medical Expenditure Panel Survey (MEPS) is a set of large-scale surveys of families and individuals, their medical providers, and employers across the United States. MEPS is the most complete source of data on the cost and use of health care and health insurance coverage.

The Pediatric Participant Use Data File (PUF) is a Health Insurance Portability and Accountability Act (HIPAA)-compliant data file containing cases submitted to the American College of Surgeons National Surgical Quality Improvement Program Pediatric® (ACS NSQIP Pediatric®). The PUF contains patient-level, aggregate data and does not identify hospitals, health care providers, or patients. The ACS NSQIP Pediatric collects data on approximately 120 variables, including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures in both the inpatient and outpatient setting. The intended purpose of this file is to provide researchers at participating sites with a data resource they can use to investigate and advance the quality of care delivered to the surgical patient through the analysis of cases captured by ACS NSQIP Pediatric. Additional procedure-specific PUFs are available for appendectomy, spinal fusion, and cerebrospinal fluid shunt.

The Federal Transit Administration's National Transit Database (NTD) records the financial, operating and asset condition of transit systems. After data reporting was required by Congress in 1974, the NTD was set up to be the repository of data about the financial, operating and asset conditions of American transit systems. The NTD is designed to support local, state and regional planning efforts and help governments and other decision-makers make multi-year comparisons and perform trend analyses. It contains a wealth of information such as agency funding sources, inventories of vehicles and maintenance facilities, safety event reports, measures of transit service provided and consumed, and data on transit employees. Those receiving funding from the Urbanized Area Formula Program (5307) or Rural Formula Program (5311) – are required to submit data to the NTD in uniform categories. More than 660 transit providers report to the NTD through the Internet-based system.
