Paris is blaming Airbnb for population declines in the city center.
Paris is one of the most popular tourist destinations in the world, and thus also one of Airbnb's most popular cities, and since 2009, many people have transformed their primary residences into 'seasonal tourist rentals.'

Between 2009 and 2014, the city lost more than 13,000 residents in its major neighborhoods, according to the daily paper Le Parisien.
The mayor of one Paris district is pointing the finger at Airbnb, calling it a 'catastrophe' for the center of the city.
However, 13,000 residents equals only about one percent in each of the districts over a span of five years.
Some of that drop may be from an increase in the number of homes being rented to tourists.
But a drop in birth rate could also be a factor.
To fight people leaving the Paris city center, officials say they'll increase taxes on second homes.
This isn't the only fight the home-sharing network has faced.
Last year, Berlin banned people from renting more than 50 percent of their apartment under short-term leases without a permit.
Some months after that, Airbnb filed a lawsuit in New York for passing a bill that bars rentals under 30 days in apartment buildings if the owner or tenant isn't there during a guest's stay.
The lawsuit was later dropped.
Airbnb has filed other suits in San Francisco and Santa Monica, California. It's also hit roadblocks in Amsterdam, London and Barcelona, Spain.
