Incidence of Osteopenia and Osteoporosis seems to vary by country. Osteoporosis is estimated to affect 200 million women worldwide.... "the age-adjusted incidence rates are many times higher in affluent developed countries than in sub-Saharan Africa and Asia." http://www.who.int/nutrition/topics/5_population_nutrient/en/index25.html
Latin America. A 2012 study states that "Data for osteopenia and osteoporosis in Latin America are scarce. Research conducted in Argentina has revealed that one out of four women aged above 50 years has normal bone mineral density, two have osteopenia, and one has osteoporosis. Other countries participating in this audit revealed similar rates of osteopenia and osteoporosis using smaller non-population based studies." https://www.iofbonehealth.org/sites/default/files/media/PDFs/Regional%20Audits/2012-Latin_America_Audit_0_0.pdf
European Union. In 2010 there was a large study done Incidence of Osteopenia, Osteoporosis in the European Union. That study can be accessed at this link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3880492/
As for fractures. We do have the results of a study of hip fractures by nation. Whether the incidence of fracture is related to diet, types of activity or genetic disposition is not identified...only the rate of fracture by nation.
The graph of hip fractures by country can be seen here: https://www.whitelies.org.uk/sites/default/files/milkmyths/sites/default/files/graph.jpg
