We have a rich resource of phenotypic, environmental, genetic and linkage data gathered from different cohort groups over almost 25 years. Our data dictionary (zip file, 213MB) provides an overview of all the data we hold. Our variable catalogue (zip file 2MB) shows every single variable name and label, grouped according to data source. You will need this if you are a researcher planning to make a formal request to access our data. You can also find out about our future data collection plans in the ALSPAC New Data Collection Plan 2015-2019 (PDF, 188kB).
