Other changes were a rising birth rate. In 1955, the Māori birth rate was nearly double the European rate at 43.6 compared to 26 per 1000. At the same time, Māori had fewer qualifications. In 1956 6.5% of Māori held professional, managerial or clerical jobs compared to 26.7% non-Māori. As a result, only 3.36% of Māori earned 700 pounds or more per annum compared to 18.6% for non-Māori. Māori were significantly impacted by changing economic circumstances such as the drop in wool prices. This made Māori more vulnerable to economic and social deprivation. King says that the lower Māori educational attainment lead to lower income jobs, which led to lower income, poor housing, and poor health, which in turn led to higher rates of crime.
