The type of dwellings that a certain group of people has can tell a lot about the society of that particular group. In this case we have the Karankawas that had homes easy for transportation, and the Caddos that had permanent homes of heavier build.
We can conclude that the Karankawas were nomadic people that were constantly on the move. They have lived in areas that were not suitable for agriculture, so they were hunting and gathering in order to get the needed food. This means that the societies were not large, but consisted of smaller number of people, and the groups were made out of the extended family or few families.
The Caddos, on the other hand, were having sedentary life according to their dwellings. They most probably lived in area suitable for agriculture, so they produced their own food, thus having no need to change their location of living. The societies were larger and more complex, as it was possible with the surplus of food, but also practical for development, and defense in case it was needed.
After 1880 the bulk of immigrants going to the U.S. were coming from Europe.
