Religion-based Urbanization Process in Italy: Statistical Evidence from Demographic and Economic Data

TL;DR

This study investigates the demographic and economic characteristics of Italian cities with Saint names, revealing strong correlations and a significant Saint effect on urbanization patterns through statistical analysis of census and tax data.

Contribution

It introduces a novel approach to analyzing urbanization by focusing on hagiotoponyms and provides empirical evidence of the Saint effect on demographic and economic variables.

Findings

Strong Saint effect influences city demographics and economy.

Significant correlations between Saint popularity and city wealth.

Distribution patterns highlight cultural impact on urbanization.

Abstract

This paper analyzes some economic and demographic features of Italians living in cities containing a Saint name in their appellation (hagiotoponyms). Demographic data come from the surveys done in the 15th (2011) Italian Census, while the economic wealth of such cities is explored through their recent [2007-2011] aggregated tax income (ATI). This cultural problem is treated from various points of view. First, the exact list of hagiotoponyms is obtained through linguistic and religiosity criteria. Next, it is examined how such cities are distributed in the Italian regions. Demographic and economic perspectives are also offered at the Saint level, i.e. calculating the cumulated values of the number of inhabitants and the ATI, "per Saint", as well as the corresponding relative values taking into account the Saint popularity. On one hand, frequency-size plots and cumulative distribution function plots, and on the other hand, scatter plots and rank-size plots between the various quantities are shown and discussed in order to find the importance of correlations between the variables. It is concluded that rank-rank correlations point to a strong Saint effect, which explains what actually Saint-based toponyms imply in terms of comparing economic and demographic data.
