  • Crude rates are helpful in determining the cancer burden and specific needs for services for a given population, compared with another population, regardless of size.
  • The French Institute for Demographic Studies or INED, is a public research institute specialized in population studies that works in partnership with the academic and research communities at national and international levels.
