Model Construction

Limited Enthusiasm

The model of short-term revival growth, based on the analogy with the spread of a disease.

Demographics

The limited enthusiasm model with births, deaths, reversion & secularisation.

Renewal

Allows for enthusiasts to be made from existing inactive believers.

Spiritual Life

Enthusiasts can build the spiritual life of the church, which in turn improves their effectiveness

Migration

Adding migration investigates revival in growing communities

Membership

Separating attendance from membership to investigate their correlation with growth and decline.

Aging and Church Decline

Aging effects the Demographics model if the church is in steep decline. Thus corrections are needed.

Limited Enthusiasm Results

Enthusiasts are the subset of the church who are active in the conversion of unbelievers. They are "infected" with religion and pass it on to their friends, family and contacts. The result is the religion spreads like a disease, and the church grows.

In the basic model new converts are the primary source of enthusiasts because they have the most contacts with unbelievers. Extended models include births as a source of believe
