The United States gets the most tornados than any other country, nearly four times more than Europe, excluding the small stuff.
This is most due to the fact that there aren't any major east to west mountain ranges to impede a torndadoes progress, like other countries and continents have in their topography. America is surrounded by oceans and the Gulf of Mexico, all of which are liable to have storms of all kinds, especially when the Atlantic tagteams with the Gulf, which results in a Katrina.
Tornadoes have occurred in all 50 states. However. Most tornadoes happen in or near the area known as tornado alley, which extends north from Texas to South Dakota and includes parts of some adjacent states.

The majority of UK tornadoes are not recorded. So most statistics on the number of recorded tornadoes in the UK are usually around 70. Most UK tornadoes happen in the countryside (so don't get noticed) and are very small (usually). It is common belief that more tornadoes happen in the UK than in the US (tornado ally included) - Although US tornadoes are way bigger and stronger than those in the UK and so more are likely to be noticed and therefore recorded. Tornadoes in the UK usually happen in the summer when the weather conditions are right.
Tornadoes always happen during thunderstorms. They cannot occur without them.
Normally in the Spring and early summer. But tornadoes can happen all year long.
Tornado's normally in occur in Texas and the USA but other places too.
Supercells are normally associated with tornadoes.
Normally tornadoes happen in late spring or summer. I would say 75 or 80 degrees for that reason.
That depends on what you mean by "mini tornado" as it has no real definition. If you mean small, weak tornadoes, then yes. Even in areas prone to large tornadoes, the smaller ones will still be in the majority. However, weak tornadoes are rarely heavily covered unless they strike in places not not normally associated with tornadoes.
Tornadoes can happen in any place that gets thunderstorms.
Tornadoes happen in Miami for the same reason they happen anywhere else. See the related question for how tornadoes form in general.
