D. Immigrants may not have the skills necessary to find work

Explanation:

The majority of the immigrants that came into Europe in the past few years mostly moved into the most developed countries of Western Europe and Scandinavia. These countries offered very good conditions for the immigrants so that is why they preferred them. The problems is that the majority of the immigrants came from less developed countries where the economies are totally different. Because of that, the majority of them have skills that are suitable for those types of economy, but do not posses the skills to be effective and productive in the well developed industrialized economies. This resulted in the majority of them to be not be able to find proper work, and they are using money from the social welfare, which in turn is not seen fondly by the native population who contributes for those money.

the density would be a smaller number.
