of medical services in the countries. IMR is an effective resource for the health department to make decision on medical resources reallocation. IMR also formulates the global health strategies and help evaluate the program success. The existence of IMR helps solve the inadequacies of the other vital statistic systems for global health as most of the vital statistic systems usually neglect the infant mortality statistic number from the poor. There are certain amounts of unrecorded infant deaths in the rural area as they do not have information about infant mortality rate statistic or do not have the concept about reporting early infant death. Europe and US The exclusion of any high-risk infants from the denominator or numerator in reported IMRs can cause problems in making comparisons. Many countries, including the United States, Sweden and Germany, count an infant exhibiting any sign of life as alive, no matter the month of gestation or the size, but according to United States some other countries differ in these practices. All of the countries named adopted the WHO definitions in the late 1980s or early 1990s, which are used throughout the European Union. However, in 2009, the US CDC issued a report that stated that the American rates of infant mortality were affected by the United States' high rates of premature babies compared to European countries. It also outlined the differences in reporting requirements between the United States and Europe, noting that France, the Czech Republic, Ireland, the Netherlands, and Poland do not report all live births of babies under 500 g and/or 22 weeks of gestation. However, the differences in reporting are unlikely to be the primary explanation for the high rate of infant mortality in the United States' compared with its peer countries at a similar level of economic development. Rather, the report concluded that the primary reason for the United States' higher infant mortality rate when compared with Europe was the United States' much higher percentage of preterm births. Until the 1990s, Russia and the Soviet Union did not count, as a live birth or as an infant death, extremely premature infants (less than 1,000 g, less than 28 weeks gestational age, or less than 35 cm in length) that were born alive (breathed, had a heartbeat, or exhibited voluntary muscle movement) but failed to survive for at least seven days. Although such extremely premature infants typically accounted for only about
