There are two reasons.
First, the central United States has an ideal Climate setup for tornadoes in the spring and early summer. Warm, moist air comes in from the Gulf of Mexico and cool air from Canada and/or dry air from the Rockies . This triggers thunderstorms. Initially either development is held back by a layer of stable air called a cap, which allows instability to build until the storms can break through it. When they do, the added instability makes them stronger. Finally, strong upper level winds create wind shear, which sets thunderstorms rotating, allowing them to produce tornadoes. Similar conditions can occur elsewhere, but not as often.
A second important factor is that the United States only gets a large majority of recorded tornadoes, not all tornadoes. The National Weather Service puts effort into documenting as many tornadoes as possible, even the weakest of them. Most other countries do not conducts extensive damage surveys, so most tornadoes that occur are never recorded unless they cause major damage.

Are there tornadoes in all 50 states?

Are 75 percent of the Earth's tornadoes in the US?
No. The reality is that 75% of Earth's recorded tornadoes occur in the United States. The United States is one of few countries to actively monitor and survey tornadoes within its borders, so most tornadoes that strike the U.S. are recorded. In most other countries the majority of tornadoes likely never get recorded, resulting in highly inaccurate statistics.
Where do tornadoes occur most frequently?
Tornadoes occur the most in Tornado Alley, a region in the United states that includes Texas, Kansas, Oklahoma, Nebraska, Missouri, South Dakota and Iowa. While tornadoes can occur elsewhere, nowhere else in the world do they occur more frequently.
What percent of tornadoes occur in United States?
75 percent of recorded tornadoes occur in the U.S. However, this is misleading as unlike the U.S. many countries do not keep records, resulting in tornado numbers outside the U.S. that are unrealistically low.

Approximately 75% of tornadoes occur in the United States, which is in the western hemisphere. Therefore, around 25% of tornadoes hit the eastern hemisphere in a year.

In the US what time of the year do tornadoes usually occur?
Tornadoes tend to occur during late spring to early summer in the United States.

80 percent of tornadoes occur between March and June, with the peak tornado season typically falling in May in the United States. Tornadoes can happen at any time of the year, but spring and early summer are the most active periods due to the clash of warm and cool air masses.
