Despite the regime's constitution guaranteeing religious freedom, this annual report for 2011 on the state of religious freedom around the world indicates that there has been a continuation of the complete restriction of religious freedom in North Korea. As accurate reports from within the country itself are all but impossible to come by, the report uses a variety of external sources for the basis of the report. The indication is that whilst the freedom of citizens to worship as they please has not deteriorated further, it has not improved at all meaning that North Koreans are still some of the most restricted when it comes to religious freedom. The US has continued to press for change in religious freedom in North Korea, but to no avail.
