Studying Populations & Epilex

Studying Populations is a computer assisted learning package for epidemiological methods. It is suitable for anyone working in health sciences including medical students, Masters students, public health practitioners and clinicians. It covers many basic epidemiological concepts in a set of over 80 interactive exercises and simulations.

The package includes a glossary based on definitions in the IEA sponsored 6th edition (2014) of the Dictionary of Epidemiology.

Update (December 2017)
SP 4.0.2 has had minor corrections to the text layout and up-to-date references have been added to the commentary on questionnaire design. We recommend you download and read the instructions for installation for this version before installing the package on your computer.
A Toolkit is available for modifying the package to make it more relevant for students outside the UK. It comes with full instructions in its help file. This revised toolkit only works with Studying Populations version 4.

Update (September 2017)

An updated version 4.0.0 in Spanish is now available. Changes since version 3.0.9 are recoding to allow popups to work with Windows 10 and corrections to typographical errors.


Epilex is a Multilingual Lexicon of Epidemiological Terms. You may pair any two languages in the alphabetic order of either one. You may print the pairings most useful to you, thus allowing the building of personalized lexicons.
