The city of Madrid has a population of around 3.5M, while the Community of Madrid has over 6M people (maybe even 7M, not sure). However, the Community of Madrid compiles the whole province of Madrid, with all 179 municipalities.
You're mistake stems from confusing different metrics. There is difference (for example in context of Paris) between the so-called 'agglomeration', 'metropolitan area' and the actual inhabitants of the city. While in LA, for example you can't really feel the difference between leaving LA and being in LA, in european cities like Berlin and Paris, the difference is very visible. 'Potsdam' for example, would by American standards probably be considered a suburb of Berlin, while in reality it's the capital of a different state.
