The research design that was used to collect this data was to investigate the rate of deaths that were experienced among the immigrants since the enactment of the immigration policy. The data used for the research was collected from multiple sources. The main source was from the immigration department. The records gave the rate of deaths that were experienced among immigrants on a yearly basis. Information from the National Vital Registration System as well as the statistics from the BSI Incident Tracking System was used to collect the data. These were methods identified to give a clear report of death incidences that were recorded over a period of time. The sampling method that was used included comparison of cases that were reported using both methods. They were compiled to see whether the rate of deaths reduced or increased after the immigration policy was passed in parliament. There was however a slight difference in the results due to the sampling methods used.
The dependant variable for this data was the deaths of immigrants that were experienced over the years. The information was obtained from both national and state registration centers and compiled to find out on the changing rates observed. The time limit that was used to collect the data was from 1984 to 2003. This was the time when immigrant deaths were rampant and hence appropriate for the study. The findings of the research revealed that the immigration policy did not help much in reducing the rate of deaths among immigrants. It was expected that the rate of crime reduce after the policy was enacted. It was hence identified that there are other factors that led to such deaths that could not be minimized by the enactment of this policy. The above findings could not be considered absolute because of certain limitations. Even though the overall results showed that the aggregate number of deaths on immigrants did not reduce, it was contrary to information that was collected on state level. The fact was that the immigration policy helped to minimize deaths in certain states by a considerable percentage which the aggregate analysis could not show.
