news stations in the United States all had average viewer ages' within the Baby boomer range. In 2019, advertising platform Criteo conducted a survey of 1,000 U.S. consumers which showed baby boomers were less likely than millennials to purchase groceries online. Of the baby boomers surveyed, 30 percent said they used some form of online grocery delivery service. Life expectancy Around the world, people are living longer than ever before. Global life expectancy has increased from 47 years in the 1950s to over 72 years in 2016. As a result, the number of people older than 60 years of age has gone up over the decades, as has their share of the global population. However, the rate of population aging in the developing world is faster than among developed nations. Asia, South America, and the Caribbean are all aging rapidly. Globally, the ratio of the number of working-age people (15-64) to those aged 65 and over—the support ratio—has fallen from 11.75 in 1950 to 8.5 in 2012 and is on course to drop even further in the upcoming decades. These developments will fundamentally change the patterns of consumption in the global economy. The global disease burden will also change, with conditions affecting the elderly, such as dementia, becoming more common. As countries around the world face the problem of a 'boomer dense' population, they find their tax revenues and what they can spend on elderly support in decline. Some countries, such as Japan, South Korea, and Singapore, have invested considerable sums of money on a variety of novel medical devices, robotics, and other gadgets to assist the elderly in their sunset years. Others, such as Austria and the Netherlands, have created specialized services for the elderly, among them dementia-friendly villages decorated with items and music from the 1950s and 1960s to help residents feel at home. Meanwhile, Hong Kong, Taiwan, and India passed legislation to incentivize people to provide more financial support for their elders. In the United States, the sheer number of baby boomers can put a strain on Medicare. According to the American Medical Student Association, the population of individuals over the age of 65 will increase by 73 percent between 2010 and 2030, meaning one in five Americans will be a senior citizen. Political evolution In Europe, the period between the middle to the late twentieth century could be described as an era of mass politics, meaning
