I think it’s more useful to OP to provide some context for the numbers. The 2 million people in Houston are spread over a very large area. In fact, Houston’s population density is only 1/3 of Evanston’s. The high population density of Evanston is reflected by the fact that Northwestern students have 100 eateries within walking distance (Evanston downtown and Central street). While Evanston is suburb, it offers benefits of high-density urban living and high walkability; it borders Chicago and it’s easy to travel to Chicago through public transit. On the other hand, while Houston is technically a city, in substance, it’s basically a cluster of many suburbs. Popular hangouts are in the form of malls or strip malls.
