Which occupation group among the immigrants was consistently the largest? why do you think so many people from that group immigrated to the united states? does this chart contradict immigration of today? provide examples and details to support your answer.

1. The occupation that constantly the largest is labor workers.
2. The reason for this is because many of the immigrants are willing to taking up the labor with lower than average prices. On top of that, United States provide a lot of opportunities for labor jobs
3. Today, i believe more and more immigrants are tilted to professional jobs because one of the most requested occupations from united states toward other companies is technology related-jobs.
