Population size, hip fracture cases, annual incidence rates, and average annual change of hip fracture incidence rates in the Austrian population ≥ 50 years 2009–2018. Numbers of hip fracture cases are based on a correction factor of 0.9 that was applied to aggregate data throughout to account for multiple registrations due to the same fracture
