"As we usher in 2020, the total global population will have reached 7.8 billion. Across the globe, more of us live in cities than in rural areas, and that percentage is expected to increase into the future. In fact, the United Nations predicts that 68% of global citizens will reside in urban areas by 2050.
With a continuously rising urban population, infrastructure planning becomes even more vital to the health and happiness of all people. Of course, exercise, proper sleep, and socialization are keys to a happier life, but infrastructure plays a major role as well. Researchers have even found strong links between poor infrastructure and a reduced quality of life. Thoughtful city planning and investments in stable infrastructure are also integral to alleviating poverty while also creating jobs."
