Texas is a vast state, with an area of 678,052 square kilometers, while New York is much smaller, with an area of 122,283 square kilometers. This means that New York is only 18.03% the size of Texas. In terms of population, Texas has 25.1 million people, which is 5.8 million fewer than the population of New York. The region of New England is bordered by the state of New York to the west and the Canadian provinces of New Brunswick to the northeast and Quebec to the north.

When Texas joined the Union it was already a large independent republic and was not divided.
