Maslow’s hierarchy-of-needstheoryis used to predict development of Quality of Life (QOL) in countries over time. Previous data sets have not had sufficient power to test these development trends among countries. Therefore a new database was developed that includes annual quality of life time-series for 88 countries from 1960 to 1994, covering measures on all five of Maslow’s need-levels. Results showed significant agreement with some of Maslow’s predictions, including his sequence of need achievement, and parts of an S-shaped trajectory in QOL. However, his mechanism of growth – that countries must slow growth in one area to increase growth in another – was disconfirmed.
