The study, started in the 1970s in Matlab, compared a group with access to contraception and birth-control education to a similar group that did not have access to those things.
In 1972, Campbell's university began a project to track the success of a group of preschoolers and a similar controlgroup of kids who were not given access to preschool.
The group also wants stricter control from the government for vehicles entering the country from abroad and better access for the unemployed to all local job vacancies.
