Scholars have shown a special interest in discovering and studying the role of ethnic diversity and spatiality at the country and region levels. This study contributes to the theoretical debate on the spatial dynamics of ethnicities, with the aim of (1) determining the evolution of ethnic dynamics in post-communist Romania and (2) applying ethnic fractionalisation and polarisation indices. The study uses a mixed methods approach based on a descriptive statistics analysis and applies the fractionalisation and polarisation indices to Romania’s NUTS-3 (i.e., county) level. The findings suggest that the ethnic spatial dynamics in post-communist Romania have shown a decrease in all ethnicities due to migration and low birth rates, with the exception of the Roma ethnicity, for whom the trend is increasing. Additionally, polarisation and fractionalisation indices have different evolutionary manifestations depending on the dynamics of the ethnic groups present in certain geographical areas. Although neither of the two analysed indices has witnessed profound change at the spatial level, these small changes in spatial and short-term ethnic diversity can help us advance knowledge about co-existence in ethnically diverse societies. Higher values of the two indices are obvious in several counties where ethnic Hungarians cohabitate with Romanians and other ethnicities. This discovery can inform policy-makers to implement more policies for the further peaceful co-existence of Hungarians, Romanians, and other ethnic groups in Transylvania and other western counties in Romania. Furthermore, as the population growth trend for the Roma ethnicity is upward, Romania has to implement proper policies and build better government infrastructure to counter social inequality against the Roma people. This will help curb potential conflicts between the Roma and other ethnic groups at the local level. Finally, as most ethnicities decreased in number in post-communist times, further attention needs to be paid to the erosion of ethnic diversity in Romania because this could have a negative impact on economic development, social trust, and democracy.

This study explores religious diversity in Romania and how the trends of indices of religious fractionalization and polarization manifest at the county level in a post-communist period. The county level was selected as the relevant level for analysis due to its more clearly visible spatial dynamics with regard to religions. Recent studies have revealed that the erosion of diversity is an important aspect for any country and needs to be considered as an important aspect of democracy. This paper highlights how digital mapping of religious polarization and fractionalization in Romania has been generally maintained, although the regions of Transylvania, Banat, Dobrogea and Western Moldova remain areas in which there are different religions. Other than the general aspect of religious diversity depending on ethnic trends, there has been a rise of Pentecostals and Baptists at the county level. This aspect has further implications for our study, which calls for creating new institutions for dialogue between majority Orthodox communities and Protestants, not only so that potential conflicts do not appear between Orthodox and emerging religious communities but also to ensure objective, cultural, religious coherence. Our maps revealed the distribution patterns and the temporal evolution of religious denominations for the 1992–2011 period. The major line of originality in our research rests in the findings that after conducting a bivariate spatial autocorrelation analysis of religious fractionalization and polarization, we were able to identify two distinct clusters with spatial overlap over historical provinces.

This study explores religious diversity in Romania and how the trends of indices of religious fractionalization and polarization manifest at the county level in the post-communist period. The county is selected as the relevant level for analysis due to its spatial confessional dynamics being more clearly visible. Recent studies have revealed that erosion of diversity represents an important aspect for any country and needs to be considered as an important aspect of democracy. This paper highlights that religious polarization and fractionalization in Romania has been generally maintained, although the regions of Transylvania, Banat, Dobrogea and Western Moldova remain areas where there are different confessions. Besides the general aspect of religion diversity depending the ethnic trends, there is a rise of Pentecostals and Baptists at the county level. This aspect can inform policymakers to create new institutions for dialogue between majority Orthodox communities and Protestants so that potential conflicts do not appear between the Orthodox and emerging religious communities, but also to ensure objective, cultural, religious coherence.
