Long Term Growth

Church of England 1979-1998

Application of the Limited Enthusiasm Model with Demographics

The Church of England is in decline. Based on church attendance surveys its attendance has fallen from 1.7 million in 1979, through 1.3 million in 1989 to 980,000 in in 1998. Fitting this to the general limited enthusiasm model gives a reproduction potential of 1.08, under the extinction threshold of 1.11. Thus the church is heading for extinction but over a very long time scale. Extrapolating the model into the 21st century show the attendance down to half a million by 2022, and a mere 80,000 by 2100 (graph below). If this forecast is correct the church will be a very different institution by the end of the 21st century with most parishes completely closed.

Remarkably the attendance of the church will be less than that of the new churches by 2025 as they are undergoing revival growth. As there are similar growing congregations in the Church of England the above forecast maybe pessimistic because the evangelical and charismatic revival could become the dominant force in the Church of England. However there is no reliable data to determine these effects numerically, and that revival could be coming to an end.

As noted above the reproduction potential is not far below the extinction threshold. A number of scenarios can be given that would see the decline slowed or reversed (graph below).

Curve 1 is the extrapolation based on current figures. Curve 2 shows the effect of keeping all the children in church. The church avoids extinction but the decline is very similar. Curve 3 shows the effect of halving the adult reversion. Although the loss of children and teenagers is tragic, they can get converted later in life. The main losses are among adults.

Curve 4 is with the child loss stemmed and the adult losses halved. This time stemming child loss has more effect, as it is not swamped by adult losses. Curve 5 is with no child losses and the adult reversion a quarter of its current rate. This is enough to tip the church into revival growth. Of course an increase in enthusiasm, i.e. the reproduction potential, would have far more effect. However it does show what could be achieved if losses were stemmed.

Updating the result for the 2005 church census figures has the Church of England just on the border of extinction, an improvement over 1998. Further updates to 2011 increase confidence that the church will avoid extinction.

Updates using the Church of England's own data for 2001-2012 paints a similar scenario, with the Church of England either just above or just below the extinction threshold. Thus extinction may be avoided. This is a much better position than the Methodist, URC and Catholic denominations in the UK, and the Church of England should survive the century giving hope and time for recovery.
