Current shortages bear a closer resemblance to food emergencies in market and transition economies, where access to food is determined by one's capacity to command resources in the marketplace. This type of emergency is no less severe, but poses different challenges to outside donors. Food is distributed to the civilian population of North Korea through two channels. Workers on state and cooperative farms account for roughly 30 percent of the population, and most of these farmers are granted an annual allotment of grain at the time of the harvest. However, the country is highly urbanized, and the bulk of the population is fed through the PDS. The PDS distributes food as a monthly or biweekly ration. Rations, in turn, vary according to occupational status and age. For example, high-ranking party, government, and military officials are fed through separate distribution channels and receive higher rations, as do certain classes of workers. In confronting the fundamentally non-cooperative stance of the North Korean government, the humanitarian community has pursued two basic strategies to guarantee the integrity of its assistance: the targeting of vulnerable groups, and the monitoring of food deliveries to assure that these targeted populations are being reached. At virtually every point, the North Korean government has placed roadblocks in the way of the donor community in North Korea, which succeeded to the extent that it did only through extraordinary perspicacity and flexibility. Yet, even by its own admission, this monitoring effort is a leaky sieve, and it is estimated that between 10 and 30 percent of food aid is diverted. Most concerns with diversion center on the appropriation of food by the military. Military and party elites have other sources of food; an equal if not greater problem is the diversion of food to the market or to less deserving groups. Also, the remote regions that suffered from the most severe famine conditions were the first regions to stop receiving shipments of food supplies, and at the same time, as local industry collapsed, residents' purchasing power decreased. Restrictions on the freedom to move caused the so-called 'hostile class' ‒ whose members were relocated to remote mountain areas ‒ to suffer from the limited access to food. A UN human rights office report released in May 2019 highlighted the "appalling" levels of hunger that have been affecting around 10.9 million people particularly in north-eastern and rural provinces of North Korea.
