Some space launches are made from Florida, some from Texas, some from California and so on.
Which US states and territories had the most orbital space launches in all space history?
I mean launches that put something into orbit.

Using Jonathan's list of orbital launches, which is pretty widely considered to be the best source for such information. I'm looking at attempts, not successes, so take that in to account. I'm also including deep space launches, as they were usually in orbit for a short period of time before going to deep space.
Also of some note is the Pegasus launches. These are airborne, so they don't follow the normal parameters, but I'm going to count then from where the plane took off.
So let's then add these up by state!
So it seems the order, including US controlled regions that aren't states, is Florida, California, Virginia, Marshal Islands, and Alaska. I'm sure the statistics for successful launches will preserve that order.
States with no coastline to the atlantic or pacific ocean could not be used for orbital launches with a low inclination, orbits with much distance to the poles. The risk of rocket parts falling down on the ground instead into the ocean should be avoided. The trajectory of the rocket should not cross land after leaving the launch pad for the next hundreds of kilometers.
A launch to retrograde orbit is possible from California, but most orbits are prograde and need the east coast. Polar orbits are possible from the west coast too.
Only some military launches may be done far away from the coast. No insurance company would accept the risk of rocket parts falling on the ground for an affordable premium.
Launches done far away from the equator are more expensive than those close to the equator, therefore you will find very few launches from the northern states.
