This is the histogram for year of birth from the church rolls database as at Feb 2013. Note that only about half of individuals in the database have year of birth recorded.

This is the histogram for the number of planned givers and the value of their giving, split by age of the givers. It only includes those with a fixed amount of planned giving, and so under reports total income. "NoDoB" indicates that no date of birth is recorded in the church rolls database for that giving unit.

Application of standard Australian actuarial data, assuming that the un-recorded dates of birth are distributed similarly to the recorded ones, leads to a most probably prediction of 15% of income to be lost by death in the next five years.

This is the histogram of postcodes for families in the church rolls database. Note the dominance of 3150.
