referenssiikäryhmien
Referenssiikäryhmät, often translated as reference age groups, are statistical constructs used to standardize comparisons across different age distributions within a population or sample. They are particularly relevant in fields like epidemiology, public health, and demography when analyzing health indicators, disease rates, or mortality data. The primary purpose of a reference age group is to account for the influence of age structure on these indicators. Without standardization, observed differences between populations or time periods might be due to variations in age composition rather than true differences in the phenomenon being studied.
These groups are typically defined by specific age ranges, such as 0-4 years, 5-9 years, and so
