URBAN OBESITY

"The number of people living in urban areas will increase ever rapidly. Urbanization – the demographic transition from rural to urban – is associated with shifts from an agriculture-based economy to mass industry, technology and services.

For the first time ever, the majority of the world’s population lives in a city, and this proportion continues to grow. A hundred years ago, 2 out of every 10 people lived in an urban area. By 1990, less than 40% of the global population lived in a city, but as of 2010, more than half of all people live in an urban area. By 2030, 6 out of every 10 people will be living in a city, and by 2050, this number will have increased to 7 out of 10 people.

Currently, around half of all urban dwellers live in cities with between 100.000 – 500.000 people, and fewer than 10% of urban dwellers live in mega cities (defined by UN HABITAT as a city with a population of more than 10 million)."
