Denmark is known for many things – the Vikings, pastry, Hans Christian Anderson, Viggo Mortensen – and as a place full of beautiful people who have never been shy about sex. But even that hasn’t produced what Denmark really needs, and that’s babies.

“Can sex save Denmark’s future,” asks a promotional video from a Danish travel company. It’s running a contest to rescue the Danish birthrate, which is the lowest in 27 years.

The contest is driven by a single statistic: Danes have 46 percent more sex when they visit cities like Paris for the holidays.

It works like this: couples go online and enter the start and end dates of their most fertile period of the month. It makes them eligible for the ovulation discount.

They then enjoy their discounted trip. The promotional video, by the way, focuses on Paris and uses many suggestive shots of the Eiffel Tower. It includes helpful tips too. For example, tip #2: Men, avoid tight pants, and tip #6: don’t forget to have sex without protection.

Then, after a few weeks with some skill and a little luck, you send in your positive pregnancy test, along with the pregnancy chart provided by your doctor – and you win a three-year supply of age-appropriate diapers, and a stroller to go along with Denmark’s newest citizen.

According to The New York Times, in the year since this campaign started, Denmark saw an uptick of 1,000 births. It’s the first increase in four years.

As the video says, “do it for Denmark.”

It is amazing what a little patriotism can achieve.
