There are many variables that determine the level of health, including social, cultural, economic and other factors. One problem that may hinder the improvement of health is the accumulated socioeconomic inequality. In the past 25 years, a series of transnational empirical studies have put socioeconomic inequality It is linked to morbidity, mortality, life expectancy, and the level of medical services. Studies have found that, the same as other conditions, the more unfair a country is, the worse its health is. From this passage, we can conclude that:. ['When using and enjoying social, cultural, and economic resources, A. nationals get a lot of fairness, then the health level of A. nationals must be very high.', "In the last ten years, the national income of B. has increased, nutrition has improved, and the resources invested by the state in health care have also increased. Compared to ten years ago, the health level of B. 's nationals must have greatly improved.", 'Social, cultural, and economic inequality in a country is likely to translate into inequality in medical services, which affects the health of the people.', 'National morbidity, mortality, and life expectancy are determined by the socioeconomic equality of the country and the degree of equality.']
