How this page is built. Figures come from the official statistical releases linked above; where agencies publish provisional numbers we say so, because they are revised. Brazil’s national death data come from the Ministry of Health mortality system (SIM/DATASUS) and are usually final about two years later, and some topics, such as fires, have no single national count, so we say which year and source each figure covers. Money is given in reais (R$). Headlines and quotes are our translations from Portuguese. Photos are public-domain or Creative Commons images credited in each caption; file photos are illustrative and are not from the events described unless the caption says so. This page tracks trends and is not personal safety, medical, legal or financial advice.
