A 0.7 percent decline in livability worldwide and a 1.3 percent decrease in safety and stability are significant changes in the worldwide standard of living index as of 2015, according to Global Finance. Tunis, Tunisia; Athens, Greece; Sofia, Bulgaria; Moscow; and St. Petersburg, Russia, experienced the largest reduction in standard of living.
The Economist Intelligence Unit's global livability ranking and report reveals that Melbourne, Australia; Vienna; Vancouver and Toronto, Canada; and Adelaide, Australia, are the most livable cities across the globe. The top-ranked cities are generally midsized areas in wealthy countries with low crime levels, low population density and abundant recreational activities. Of the 10 most livable cities, eight are found in New Zealand, Canada and Australia.
The report also shows that London slipped down in the ranking due to unsatisfactory transport infrastructure and escalating social unrest, making the country the third least livable city in Europe. The lowest-ranked cities are those with significant conflicts, especially Karachi, Lagos and Damascus. Other cities with a considerable decline in standards of living in the recent five years include Tripoli, Libya; Kiev, Ukraine; Caracas, Venezuela; Cairo; and Muscat, Oman. These countries have been experiencing issues with instability, civil unrest, violence and unemployment.
The ranking offers scores for 140 cities throughout the world. The Economist Intelligence Unit used 30 qualitative and quantitative factors revolving around environment, health care, education, infrastructure and stability. Index factors include livability, safety and cost of living.
