Examples

population <- Counts(array(c(10, 15, 13, 16),
                           dim = c(2, 2),
                           dimnames = list(age = c("0-29", "30+"),
                                           time = c(1970, 2000))))
births <- Counts(array(13,
                       dim = c(1, 1),
                       dimnames = list(age = "30+",
                                       time = "1971-2000")))
deaths <- Counts(array(c(0, 9),
                       dim = c(2, 1),

                                       time = c("1971-2000"))))
account <- Movements(population = population,
                     births = births,
                     exits = list(deaths = deaths))
