Case History of Survey of Doctorate Recipients, 2015-2023

Add to My Basket

Description

The Case History of Survey of Doctorate Recipients, 2015-2023 data file supersedes the 2021 and earlier Case History and SDR-DRF files. It combines case disposition data for all cases sampled from the 2015 SDR sample and from subsequent rounds, with all non-personally identifiable information available for these cases from the SDR’s frame, the Doctorate Records Files (DRF). The DRF source used to create this file is the 2023 DRF (NOID2023), the cumulative file created from the annual census of research doctorates, the Survey of Earned Doctorates (SED). In the 2023 DRF, all geo-coded variables conform to the NCSES’s updated Taxonomy of Geographic Areas (TOGA), used in the 2023 SDR.

NCSES is updating their data linkage policy to better meet the data linkage needs of NCSES and external researchers. Currently, NCSES does not support researcher access to direct Personally Identifiable Information (PII). NCSES encourages researchers interested in developing an SAP application that includes linking NCSES restricted data to non-NCSES data sources to contact NCSES at NCSES_Licensing@nsf.gov to assess feasibility and appropriateness.

This dataset is available through the NCSES Secure Data Access Facility (SDAF), a virtual enclave that can only be accessed within the United States.

Detailed Methodology

Sample

The SDR uses a fixed panel design with a sample of new doctoral graduates added to the panel in each biennial survey cycle. SDR sample members who remain age eligible are typically retained for the subsequent SDR cycle. In addition, each cycle, a sample of 10,000 graduates who recently earned their doctoral degree is added. The new graduates sample design follows the design and sample stratification first introduced in the 2019 SDR, defined by detailed fields of study, sex, and underrepresented minority status.

Method of Data Collection
Survey (self- or interviewer-administered)
Frequency of Data Collection
Every two years
Number of Cases
Approximately 175,300 individuals are included in the dataset.
Number of Variables
285
Linkage Capabilities

The SDR Case History-DRF data can be linked to the five crosssectional SDR data (2015-2023) by the survey id, REFID, it can also be linked with other data sources by IPEDS educational institution indicator and FIPS state code.

Linkage Variables
  • IPEDS indicator for educational institutions
  • State FIPS code
  • Other (see Linkage Capabilities description)
