Much attention has been given to the causes accounting for the rise of religious movements: inequality (Linton, 1943), racism (Lea, 1926; Sundkler, 1948), relative deprivation (Barber, 1941; Aberle, 1972), oppression (Lanternari, 1963), the colonial situation (Balandier, 1970), and white power (Ifeka-Moller, 1976) are among the factors which have been given prominence. These and other similarly ‘macro-social’ factors are very visible, especially from a distance. They can be, and often are, imagined to operate with general uniformity across entire social groups. This then invites the use of similarly general demographic measures to prove both the reality of the independent variable and its efficacy in accounting for the dependent variable – the rise of new churches and/or conversion to them.
