Buildings without a known year of construction are not in the figure. The latest decade is not over, so its bar only counts up to today.If the bar for the 2020s is tall even though the decade is not over, that is not a counting error. A lot was built around 2020, and Statistics Denmark measures the same rise in completed housing: 66,896 m² in Silkeborg Municipality in 2015 and 147,387 m² in 2020, 77,163 m² in Vejle Municipality in 2019 and 188,829 m² in 2020.
