The LifePaths project is now discontinued and is no longer supported.
LifePaths is a dynamic longitudinal microsimulation model of individuals and families. Using behavioural equations estimated using a variety of historical micro-data sources, LifePaths creates statistically representative samples consisting of complete lifetimes of individuals. The model's behavioural equations generate, at sub-annual resolution, the discrete events that together constitute an individual's life history. In addition to its longitudinal capabilities, a complete set of overlapping cohorts allow LifePaths to produce accurate and representative cross-sectional results from the year 1971 onwards.
LifePaths is used to analyze, develop, and cost government programs that have an essential longitudinal component, in particular those whose nature requires evaluation at the individual or family level. It can also be used to analyze a variety of societal issues of a longitudinal nature such as intergenerational equity or time allocation over entire lifetimes.
This overview contains information on the current release of LifePaths, including a brief exposition of selected key concepts.
