Why are the jobs in each region different?

Because of the population like in Texas (where im from) we are surrounded by the gulf of mexico so we are good for transporting stuff and also we are a big city (talking bout Houston) so we need architect

Because of what resources and challenges each region present. For example, there is a large amount of jobs like shipping in port cities like New Orleans because of how close it is to the water which makes it a prime place for fishing and the transferring of materials. But in some cities, there is a large population, growing by the number, which means there more of a need for housing and public services, so careers like architecture and service jobs are needed to accommodate.
