This is the histogram for year of birth from the church rolls database as at January 2019. Note that only about 60% 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, as at December 2013. It only includes those with a fixed amount of planned giving, and so under reports total income. "NoDoB" (<1%) indicates that no date of birth is recorded in the church rolls database for that giving unit, and we were unable to make a realistic estimate. About 25% of the birth dates are estimates.

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 and 30% in ten years.

This is the plot of the sum of planned giving and open plate for the last few years. Other income, particularly rent and donations, is not shown. Donations to special projects are not included.
We engaged Carolyn Kitto in 2009 to run the GrowingGenerousGivers program, which was followed by the 2010 increase.

This is the histogram of postcodes for families in the church rolls database in January 2019. Note the dominance of 3150.

This is the histogram of the number of giving units (families or individuals) by method in January 2019.
