Code to create the sub-shares:

<code>
custCenAgeSubShares[s,byrs,acc->a] = norm (mapcat (popInDwell_hist[s,byrs,a]; \
	category=ageCustomCensusCOage); dim=ageCustomCensusCOage@ageCustomCensus)
</code>

where age is a sequence from 0 to 100 in single year steps and the ageCustomCensus set contains:

0-10
11-14
15-24
25-34
35-44
45-54
55-64
65Plus

Code to apply the sub-shares:

<code>
local popInDwellDetPlan_cat[pz,s,byrs,acc->a] = customCensusPop2[pz,s,byrs,acc] * custCenAgeSubShares[s,byrs,acc->a]

popInDwellDetBS[pz,s,a] = shrink (sum (mapcat (popInDwellDetPlan_cat[pz,s,byrs,acc->a]; dim=ageCustomCensusCOage); \
	dim=ageCustomCensus))
</code>
