Demographic Accounting Models

How does the intrinsic voting strength of two groups with different adult age structures compare? How does the annual maturation of juvenile cohorts into adult voters gradually augment a group’s voting strength over time? Answers to these questions can account for why one group registers or votes at higher rates than another. This chapter furnishes two useful demographic accounting models: one, for making an “apples to apples” comparison of political participation across groups where differing age structures obscure a true comparison; the other, to foresee the effects over time of juvenile cohorts maturing into adult voters, strengthening that group’s political participation over time.
