evidence: More than 3,500 people died during those decades of conflict known as the Troubles. And though the period largely ended with a peace deal in 1998, many of Northern Ireland’s Catholics and Protestants continue to live mostly separate lives. More than 90 percent of children go to schools segregated by religion. Some neighborhoods remain physically divided. Nearly one hundred barriers [PDF], including so-called peace walls, still crosscut the capital, Belfast. [...] Continuing Division: After the Good Friday Agreement, the cycle of tit-for-tat attacks by paramilitary groups ended. But that progress has not led to full integration between Northern Ireland’s divided communities. Instead, many Catholics and Protestants continue to live segregated from each other. Catholics and Protestant communities are sometimes physically separated by a barrier. Northern Ireland has more peace walls today than during the Troubles.
