There's a Heortling age distribution table (and a plug-in-the-numbers spreadsheet) on the Heortling Stead Project website.

After much discussion and consultation, and initial modelling by Nick Brooke, the distribution we used was based on the following assumptions:
a.. There are 4.7 births per hundred each year, distributed among 21 women of childbearing age (15-44), giving an approximate birth rate of one child per married woman every 2.5-3 years.
a.. Infant mortality is relatively low when compared with ancient/medieval populations: approximately 50% of children survive the first five years of life.
a.. Newborns comprise 4.70% of the population, children aged one to fourteen 31.90%, initiands aged fifteen to nineteen 8.30%, young adults aged twenty to thirty four, 22.10%, mature adults aged thirty five to fifty nine 24.20%, and elders aged sixty and above 8.80%. (Thunder Rebels p.18 indicates half of a stead comprise children. The statement should not be taken literally: it is meant to indicate that the population is self-sustaining. To achieve such a figure would require continual pregnancy by all fertile women.)
There's more on the site.
Cheers :)
