Help excel: click & automatically copy paste

I need some help

Let's say I have 5 different tabs named London, Paris,... Each tab contains different kind of information about the cities: population, governement,...

sheet 1 is my overview sheet where in cell A1 you can enter via data - validation one of the five city names. If I click for instance 'Paris' I would like the information that's on the sheet Paris automatically filled in the overview sheet

and to further elaborate: what if when I click Paris, I only want to get on my overview sheet the population for paris

I hope this is clear

thanks for your answers
