It is very easily noticeable that the European colonial settlements in North America were based around the eastern cost of the continent. This preference was due to multiple reasons, like safety, trade, better climate conditions, agriculture.
By creating multiple settlements on and around the coast, the colonist pretty much made a high concentration of settlements that were close to each other, and also outnumbered the native population, so they were much safer in this way.
Being close to the coast meant that the products that were produced and manufactured could be easily set on ships and ready for trade, thus making lot of profit.
The climate along the eastern coast, in general, is pretty pleasant and suitable for human life, but also for production of the plants that were providing the profit in the colonies.
