The average level of social hostilities involving religion (SHI = 4.1) among the countries where government policies or actions limit conversion from one religion to another is more than 2.5 times higher than the average level of social hostilities among countries with no government limits on conversion (1.6), as shown in the chart below. As noted in previous Pew Forum studies on religious restrictions, higher scores on the Government Restrictions Index (GRI) are associated with higher scores on the Social Hostilities Index (SHI) and vice versa. This means that, in general, it is rare for countries that score high on one index to be low on the other. On average - each type of government restriction monitored by the Sept. 2012 Pew Forum study has an association with higher social hostilities, not lower.
