North Korean leader Kim Jong-un's public appearances decreased about 30 percent this year from a year earlier, the lowest since he took power. 

According to North Korean media and data by the South Korean Unification Ministry, Kim engaged in a total of 93 public activities, including field guidance, inspections and events from January first to December 28th.

That's about 70 percent of the comparable figure for last year. 

The figure marked 151 in 2012 when he rose to power and increased to 212 the next year, but steadily decreased to 172 in 2014, 153 in 2015 and 133 last year.
