The study looked at where elderly people get their income from - the government, the market, or their families. They found that most elderly people rely on income from the market, followed by government and family. Men tend to earn more from the market and government, while women rely more on family income. Younger elderly people earn more from the market, while older ones rely more on family income. Those with higher incomes depend more on government and market income, while those with lower incomes rely more on family income. Overall, elderly people in Korea rely more on market and family income compared to Western countries, especially those who are women, have low incomes, or poor health.
