Is Texas considered the West?

Could someone please clarify for me if Texas is indeed classified as part of the West in the United States? I've heard differing opinions on this matter, and I'm genuinely curious to know the consensus. Geographically speaking, Texas borders Mexico and several southwestern states, but does this automatically make it a western state? Or are there other factors that come into play when determining its regional classification? I'm eager to learn more about this intriguing topic and hear your thoughts on it.
