When the state recently issued population projections over the next 25 years, the Monitor newsroom noticed something odd: Allenstown, a community just east of Concord that we cover regularly, was projected to lose population for a decade and then grow again – and we had no inkling of what that would cause that. Secret developments? Plans to invade the town of Epsom? Widespread delayed reproduction?
Nope – it was math. As I explain here.
