We can largely blame baby boomers for an expected 18% increase in healthcare costs by 2050. That is according to a study conducted by insurer HealthPartners based in Minnesota.

Costs are not projected to increase uniformly across major categories of medical practice, the study found. The estimated change in per capita costs due to aging will be highest in the field of kidney disorders, where spending is expected to rise by 55% between 2000 and 2050, the study said.

Per capita costs are expected to decrease for post-natal care, chemical dependency and pregnancy/infertility care as a result of the demographic shift, the study said.
