"Georgina's " Travels

So I received various postcards from Georgina's family from their new homes around the world.
~9 months after Georgina's birth she has:
1497 unique children in 79 Houses in a total of 265 rooms.
( Further analysis is hard to describe in an anthropomorphous world since data set replicas would have to involve cloning in Dave and Georgina's world.)
Taking this into account of the 1497 datasets , the distribution of number of replicas is as follows:
556/1497 datasets only have one copy.
Maximum number of copies of any "data" dataset is 20.
Maximum number of copies of any "group" dataset is 3.
Maximum number of copies of any "user" dataset is 6.
What is of concern is to me is that 279/991 user or group derived datasets have one unique copy on the grid.
