The BBC has two trusted partners that provide results - AP news agency and our US news partner CBS.
When we bring you a result, we call it a "projection". That's because our partners analyse incoming results data, and when they are confident that one candidate has an unbeatable lead in a particular race, they project the winner.
That projection is not the official result - but it nearly always proves to be correct when all the votes are eventually counted.
The final result comes when states certify the results – often days or weeks after election day.
