Purpose: Although unintentional injuries are preventable, they remain an important cause of child mortality in Europe, including Hungary. ln the last decades, many efforts have been made at national and international level to reduce them. The aim of this study is to analyze the mortality data of Hungarian children and to describe the mortality trends by sex, age group and type ol injury. Methods: Mortality data of the total population ol Hungarian children aged 0-19 years collected by the Hungarian Central Statistical Office were analyzed from 19961o2022. Age- and sex-specific mortality rates and 3-year moving averages of mortality were calculated. Results: Unintentional injury mortality decreased trom 11.36/100,000 in 1996-98 to 3.721100,000 in 2019-21, but will increase to 5.01/100,000 in2020-2022. The mostvulnerable age groups within childhood and adolescence are adolescents aged 15-19 years and infants and toddlers aged 0-4 years. At the beginning of the observation period, the death rate from all unintentional injuries was about twice as high for males as for females (15.0/100,000 vs. 76/100,000 for 1996-98). The 2:1 sex ratio remained fairly stable until 2019-21.\n2020-22, the mortality rate for women approached that of men (4.6/100,000 vs. 54/100,000). The relative risk of females for unintentional injury death compared to males increased from 50.78% to 85.58%. Conclusions: Between 1996-98 and 2020-22, the unintentional inlury death rate in the 0-19 age group decreased significantly in Hungary, butthere was a marked increase in the year 2022,aiIer the C0VID-19lockdowns. The equalizing trend in the male-female ratio is noteworthy.  Kulcsszavak: unintentional injury, mortality, epidemiology, child
