We are pleased to announce a new data product, the Gateway Harmonized Chile-Cog, which is now accessible through the Gateway Data Enclave. The Chile-Cog is a Harmonized Cognitive Assessment Protocol study using a subsample from the Social Protection Survey (SPS), the oldest and largest longitudinal panel survey in Chile, and its substudy, the Survey of Quality of Life of the Elderly (SPS-ENCAVIDAM).
While the SPS includes a nationally representative sample of around 16,000 individuals aged 18 and older in Chile, the Chile-Cog was designed to collect information on cognitive function from a representative sample of the Chilean population aged 60 and older. It was designed to have content in common with other HCAPs, and the Mex-Cog, the HCAP instrument fielded within the Mexican Health and Aging Study (MHAS), in particular.
Harmonized Chile-Cog, Version A consists of Wave 1 variables, collected from 2019 to 2020. It also incorporates some demographic data from the Gateway Harmonized SPS-ENCAVIDAM.
This dataset is provided in Stata and SAS formats through the Gateway Data Enclave. The Gateway Data Enclave is a remote-access, secure data enclave hosted on the NIA's LINKAGE platform. By using the Gateway Data Enclave, users can analyze survey data from multiple HRS-INS studies on a single platform.
For more information, visit the Gateway Data Enclave website.
For more information about the Chile-Cog study, please see our Study Overview page or the information provided by the University of Pennsylvania.
The Gateway team is soliciting applications for a half-day research workshop focused on cross-country comparisons at the Gerontological Society of America (GSA) Annual Scientific Meeting on November 4, 2026 from 10:00 a.m. to 3:00 p.m. in National Harbor, Maryland. The goal of the workshop is to support new research projects using cross-country data resources available through the Gateway to Global Aging Data.
Available resources highlighted in this workshop will include two new analysis-ready datasets designed to facilitate cross-country research on aging:
Longitudinal Chronic Conditions Dataset, which combines harmonized data from the United States and England to support research on chronic disease prevalence, multimorbidity, age at diagnosis, recent diagnosis, modifiable risk factors, and related covariates. The dataset includes longitudinal data covering 2002 to 2022, allowing researchers to examine chronic conditions and related risk factors over time and across countries.
Cross-Country Social Isolation Dataset, which combines harmonized 2017–2021 core interview data from the United States, England, India, Chile, and Northern Ireland to support research on social isolation, loneliness, social networks, family contact, social activities, health outcomes, and related risk factors.
Applications are due by Monday, August 3, 2026, and should include a brief proposal for a research project to be developed in conjunction with the workshop. Proposals should focus on analyses using one of the two new cross-country analysis datasets or other data resources available through the Gateway Data Enclave. The two highlighted datasets are available through public-use access in the Enclave. All accepted participants will be expected to create a Gateway user account and apply for a Gateway Data Enclave Workspace.
Accepted participants will be expected to begin work on their proposed projects before the workshop, including exploring the relevant Gateway Data Enclave resources and running preliminary analyses. The workshop will be collaborative: participants will briefly present their research proposals and preliminary progress during the morning session and receive feedback and hands-on assistance from the Gateway team and affiliated senior researchers.
The workshop will be limited to 20 participants. Participants will have opportunities to network with senior researchers affiliated with the Gateway, lunch during the workshop, and a $300 stipend to offset travel costs.

We are pleased to announce a major update to the Harmonized dataset from the Diagnostic Assessment of Dementia for the Longitudinal Aging Study in India (LASI-DAD), which now includes newly available data from Wave 2. The Harmonized LASI-DAD, Version B.2 includes variables of the following:
This dataset is accompanied by a codebook detailing the dataset structure and all included variables. US-based researchers can access the data in Stata, SAS, and R formats through the Gateway to Global Aging Enclave. Non-US-based researchers will have access to the updated data shortly through the AD Workbench.
We are pleased to announce the launch of the new Gateway Research Planner, a tool designed to help researchers build customized research plans by bringing together key resources across the Gateway to Global Aging Data.
The Research Planner streamlines the process of moving from a research idea to implementation by bringing together study documentation, survey questions, harmonized datasets, and harmonized variables, along with programming guidance, into a single tailored output. By selecting a primary survey measure, countries and years of interest, additional measures, and preferred software, users can quickly identify the information needed to begin their analysis.
The tool currently supports 168 survey measures across 41 countries, with data spanning 1992 to 2020, supporting a wide range of cross-national and longitudinal analyses.
The Gateway Research Planner provides the following features:
Studies and Samples: Identify relevant studies and analytic samples based on selected countries and years.
Survey Questions: View comparable survey questions across studies.
Datasets: Find relevant harmonized datasets for selected countries.
Harmonized Variables: Identify comparable harmonized variables across datasets.
Research Programming: Obtain example Stata, R, and SAS code for appending, merging, weighting, and accounting for survey design.
Similar Publications: Explore publications that use the same measures and countries.
The Research Planner is designed to support researchers at all stages of research projects, from refining a research question to initiating cross-national analysis, by bringing together relevant information from across the Gateway’s existing resources into a single tool.

The education policy seminar series will take place on the 2nd Thursday of each month at 8:00 AM US Pacific Time / 11:00 AM US Eastern Time / 5:00 PM Central European Time.
The Gateway to Global Aging Data is organizing a monthly virtual seminar series on education policy. The series is led by Dave Knapp (University of Southern California) and Mauricio Avendano (University of Lausanne). The goal of the series is to foster conversations and exchange ideas between the Gateway education team, its collaborators, and outside researchers working in this growing field. Presentations will typically feature in-progress work, and active discussion is encouraged.
Participants must register to receive seminar announcements and meeting links. To register, please submit the form with your email here. Emails will be limited to seminar announcements, and you may unsubscribe at any time.
