High youth ratio: demand for daycare and schools (more space) Example: state of palestine: for every 100 workers who work, they need to support 76% of youth, 5% of seniors. High senior ratio: demand for old age security programs, public pension, and more health care. The dependency ratios must vary among different regions. Saint john vs. toronto: toronto has higher youth dependency ratio. For every 100 people - we support 24 children, 24 seniors. Japan statistics (lots of seniors; aging population country) For every 100 people - we support 21 children and 34 seniors. If median age is low = more youths.
