Body weight in Finland describes body weight for the general population and subgroups in Finland.

Estimate is a point estimate from .
Probability distribution of body weight of adults aged 18-55yr and over 55yr were extracted from . For a given age group body weight data was summarized in terms of mean and the 95% confidence interval:
- 18-55yr: 77.6 (77.0-78.1),
- 55yr+: 76.5 (75.9-77.2).
Based on that a normal distribution was created. Since standard deviations (SDs) calculated from 2.5th and 97.5th percentiles were not exactly equal the larger SD was used as a standard deviation of a normal distribution.
Note: There was not measurements for ages 18-29yr, only for 30-55yr.
The most comprehensive information on body weights of Finnish children are gender specific growth curves. They were previously used to extract the mean and 95% confidence interval (CI) of body weight at each age (month or year) from 0 to 18 years. See results of variables: Body weight of 0-24 months old Finnish children and Body weight of 2-18 year old Finnish children. Based on this information probability distributions of body weights of children aged 0-2 years and 2-18 years were constructed. Body weights of males and females are studied separately. It was assumed that the body weight for each 1-month or 1-year age specific interval follows a normal distribution with mean being the mean reported in growth tables and standard deviation (SD) being the larger value of SDs calculated from the bounds of the 95% CI. 2500 values of body weights for each 1-month and 1-year age interval were simulated from respective normal distributions and then grouped to match groups 0-2 years (months from 0 to 24) and 2-18 years (years from 2 to 18). Since none of parametric distributions fits the resulting data sets the empirical distribution of body weights was constructed.
