General mortality

1. Key messages

2. Daily deaths are influenced by epidemics and weather conditions

A heatwave mortality peak was observed in 2019. In 2020, mortality peaks were observed from March to April, and from the end of October to the end of the year. These peaks can be explained by the COVID-19 epidemic. An additional peak was observed during summer in August, caused by higher temperatures.

In 2021, a mortality peak was observed at the end of the year. This can be explained by the COVID-19 epidemic. In 2022, a mortality peak was observed at the end of the year which can be explained by the influenza and bronchiolitis epidemics [1]. The effect of the influenza and bronchiolitis epidemics can still be observed at the beginning of 2023.

More information about excess mortality can be found on the website of the Belgian Mortality Monitoring (Be-MOMO).

3. Mortality rates

In 2023, age-adjusted mortality rates are for the first time lower than in 2019

In 2023, 111,255 deaths were observed in Belgium.

The crude mortality rate decreased in 2023 to 948 per 100,000 inhabitants, comparable to 2019 (949 per 100,000). The crude mortality rate was a bit higher in women (952 per 100,000) than in men (945 per 100,000) in 2023. After adjustment for age, a 39% higher mortality rate was observed in men (1,051 per 100.000) as compared to women (756 per 100,000) in 2023.

Over the last two decades, the age-adjusted mortality rate declined until 2019; a 40% decrease in men and a 28% decrease in women were observed between 2000 and 2019. In 2020, it has raised due mainly to the COVID-19 epidemic and reached 1,051 per 100,000 inhabitants (a 16% increase in men and 15% in women compared to 2019), the highest mortality rate since 2008. In 2023, the age-adjusted mortality rate decreased under the level of 2019 for the first time since the COVID-19 epidemic.

Age-adjusted mortality rates are lower in the Flemish region

Among men in 2023, the age-adjusted mortality rate was 25% and 15% higher respectively in the Walloon Region and in the Brussels Capital Region as compared to the Flemish Region; among women, it was 23% and 11% higher respectively in the Walloon Region and in the Brussels Capital Region as compared to the Flemish Region.

During the year 2020, the regional differentials in mortality increased. Among men, the age-adjusted mortality rate was 35% higher in the Walloon Region and 32% higher in the Brussels Capital Region than in the Flemish Region, and among women, the mortality rate was 29% and 21% higher in the Walloon Region and in the Brussels Capital Region than in the Flemish Region. The COVID-19 mortality rates observed in the epidemiological surveillance [3] have shown the COVID-19 specific mortality rates to be higher in the Walloon Region and in the Brussels Capital Region, which can explain the increase of the regional differentials in all-cause mortality.

Background

Mortality is a traditional health indicator, actually better understood as a measure of “non-health”. Although quantifying irreversible events, the mortality analysis provides unique information for public health guidance, like the importance of severe health problems, their evolution over time, and some insights on their determinants (i.e. road security and smoking behavior). It is also a health indicator that has a long tradition and is measured with more validity than any other. Indeed, death is an unambiguous event, that used to be systematically registered in vital registration systems of most countries for more than one century.

The crude mortality rate is the number of deaths in a given year divided by the population under study. This indicator is not well suited for health monitoring; mortality is indeed strongly related to age. As a consequence, aging populations are facing rising crude mortality rates even if the health state is improving.

Therefore, comparisons of mortality indicators between population groups or years should always use estimators that are adjusted for differences in age composition between the groups. In this report, the age-adjusted mortality rates are used, with the European Standard Population 2010 (ESP 2010) [4] as a reference.

In this section, we describe all-cause mortality. The specific causes of death are described in the section on cause of death.

Definitions

Crude mortality rate

The crude mortality rate is the number of deaths registered in the country divided by the corresponding population.

Age-standardized mortality rate

The age-standardization is a weighted average of age-specific mortality rates to remove variations arising from differences in age structure between population groups.
