E.g 250 000 every five years or 50 000 every year. Here net migration refers to that of persons aged five years and over at the end of th eperiod; migrant children born in the interval are treatd here as part of natural increase. Table 3 includes births both to the existing population and to migrant women. The total net migration is distributed across the age groups by multiplying the total net migration for the period by the proportion in each age group. Finally the estimated migrants in each age group are multiplied by the survival ratio of migrants to obtain the numbers surviving at the end of the interval.5-994594594594594510-142,5232,5232,5232,5232,52315-195,3105,3105,3105,3105,31020-2412,12712,12712,12712,12712,12725-2915,15715,15715,15715,15715,15730-3415,77615,77615,77615,77615,77635-399,6479,6479,6479,6479,64740-442,3272,3272,3272,3272,32745-491,5341,5341,5341,5341,53450-541,2681,2681,2681,2681,26855-5989889889889889860-6481781781781781765-6947047047047047070-7426726726726726775+2042042042042040.0Table 5: Base population and Population ProjectionsAge2010201520202025203020350-463,479208,811227,309246,382303,501423,8115-947,63664,408209,702228,195247,263304,36710-1429,93550,14366,908212,152230,638249,70015-1926,71535,22755,42372,179217,337235,81220-2458,14838,82247,32767,50884,251229,29825-2971,59573,13353,86462,34582,46699,15930-3463,83486,48588,00468,97377,34997,22135-3947,86571,92994,03095,51376,94485,11640-4432,19848,35671,49892,75194,17776,32045-4917,98132,00347,29469,19289,30490,65350-5410,77017,54930,24644,09263,92182,13355-596,67710,02115,76426,52038,24955,04760-643,6905,9728,55412,98921,29430,35065-692,0363,2785,0146,97910,35416,67470-741,1511,6532,4983,6805,0177,31475+8511,5272,3063,3794,8696,738(70+/)2,0023,1804,8037,0589,88614,052Total484,561749,3181,025,7421,312,8281,646,9342,089,714source: adapted from Don Rowland (2003) Demographic methods and concepts.Oxford: Oxford University Press

Derive the female population aged 0-4 in any year from the total births for that year from Table 2. Eg. In 2006=1395676. To get which are the female births (rather than total births), assume a sex ratio e.g 105and multiply the total births by the ratio (100/205) to get only the female births. Multiply this by the survival ratio for births.Obtain the projected population aged 5-9 in 2006 by adding together the corresponding cells in Table 2 and Table 4 and copy down formula.
