OasisR: An R Package to Bring Some Order to the World of Segregation Measurement

Abstract

Interest in social segregation measurement has increased strongly over the years and the number of segregation indices proposed in the literature have become more complex. However there are only a few software applications that can be employed to analyze social segregation, and these are usually available as a plug-in/package in geographic information system (GIS) software or as limited stand-alone application. Thus, the development of a package which exploits the power and versatility of the R environment for statistical computing and graphics would be desirable. Also, analysis of the segregation indices shows that there are ambiguities and errors in the literature, and consequently in the available software applications. This is an even more important reason why we need to develop a new tool to bring some order to the world of segregation measurement. This paper contributes also by proposing an automatic statistical testing methodology for these indices, using several resampling techniques: randomization tests, bootstrap and jackknife.

Revealing the variations in impact of economic segregation on preterm birth among disaggregated Asian ethnicities across MSAs in the United States: 2015–2017

“…A Census reference delineation file for 2017 was used to define which counties, and therefore census tracts, were part of an MSA ( United States Census Bureau, 2017 ). Tract-level household income data categorized into 16 groups were matched to MSAs and used to calculate summary MSA-level economic segregation indices using the R package OasisR version 3.0.1 ( Tivadar, 2019 ).…”

Looking Back, Looking Forward: Progress and Prospect for Spatial Demography

“…Apparicio upgraded his C#-based Segregation Analyzer to the R-based Geo-Segregation Analyzer (Apparicio et al, ). Other R-based tools included the "seg" package developed by Hong et al (2014), and more recently the ambitious attempt by Tivadar (2019) with OasisR. On the Python track, a segregation module was implemented in PySAL (Cortes et al, 2020).…”

Muster ethnischer Segregation in Deutschland - Ein Vergleich anhand räumlicher Segregationsmaße

“…Gegeben den verschiedenen theoretischen Konzepten von Segregation, gibt es eine Vielzahl von Methoden um Segregation zu messen (für einen Überblick z.B. Massey & Denton, 1988;Reardon & Firebaugh, 2002;Reardon & O'Sullivan, 2004;Tivadar, 2019). Dieser Beitrag konzentriert sich auf Konzepte der "evenness", welche Segregation durch die Ungleichheit der räumlichen Verteilung von Bevölkerungsgruppen messen.…”
