Denmark has no population policies, relating to birth rates. Denmark has increased its immigration policies from one year to three, reducing the appeal. There is little to no effect from the population policies, because there is little to no policies. Some of the effects of immigration policies include less people wanting to come to Denmark as an immigrant due to it taking 3 years for citizenship. Denmark is similar to he US when it comes to discouraging many people to have even more babies by showing the costs for doing so.
Economy is a very important part of any civilization, and the same is true for Denmark. Denmark was a very agriculturally focused economy up until around 1950. In 1950 industry and manufacturing started taking over Denmark's economy. When Denmark was an agricultural economy it had a better land to output ratio than most of the other European countries around it. Now Denmark is a mixed economy with industry and foreign trade.
