Opportunity for impact

Consistent market growth, strong global trends driving future

Aging populations

  • By 2020 double the people will be over 60 years old as in 2000

Rising healthcare costs

  • U.S. healthcare spending more than 15% of GDP, Europe not far behind
  • Costs expected to grow from $2 trillion in 2007 to $3.1 trillion in 2012

Remote and emerging markets

  • China healthcare expenditure increased from 3.7% of GDP in 1995 to 5.6% in 2007
  • India government proposed in 2008 to increase public expenditure on health care from 1% to 3% of GDP

Personal healthcare

  • 33% of medical semiconductor revenue in 2008went into consumer medical devices
