Explore data and samples

We have a vast amount of biological samples and phenotypic, environmental, genetic and linkage data gathered from different cohort groups over the past 30 years. There are several ways you can explore this resource.

Explore available data

There are three simple ways to explore the data that is available for research. 

  • Our data dictionary (zip file), which includes detailed information, including frequencies, on all the data that are currently available 

  • Our variable catalogue (zip file), which is a simple list of all ALSPAC variable names and labels that are available, grouped according to data source and timepoint

  • Our variable search tool, which allows simple searching across variable names and labels to help with identifying what data might be available.  We are aware that our search tool is currently experiencing issues, we recommend refreshing your page (it may take more one then one refresh) - this usually works. Apologies for any inconvenience whilst we investigate.

 

External search options for exploring our data include:

If we have the data and samples you require, you can make an access request.

Explore external datasets

A number of ALSPAC datasets can be accessed externally, without the need for project proposals or exec permission, for specific research or for training purposes. A list is available here.

 Cohort profiles

We have published cohort profiles for all generations of the study which provide details on recruitment and representativeness.
