The addition of dimensions beyond age and sex in multistate population projections has two major objectives: first, to increase the accuracy of the projected population by capturing the heterogeneity present in the population that could affect the overall system; secondly, and more importantly, to increase the level of information provided by the projections. This article reviews the main dimensions that have been projected in the past, emphasizing global projections of educational attainment, which have been used largely in modeling exercises outside of the demographic realm. Furthermore, we propose some other dimensions that could be projected in a multistate fashion, possibly for most countries.
