I'm looking for an effective word or words to replace immigration pattern. I use the phrase in a previous sentence, and would not like to reuse it again. I can't think of a better word choice to replace it with though, and fine with not using the immigration pattern at all, but I would like to see other options first.
Here's the text.
"This decline is primarily due to changing immigration patterns. Up until the 1980s, immigration to Sweden predominantly comprised of European labor migrants; however, since then non-European refugees and asylum seekers have begun to make up larger shares of the immigrant population. Following the shift in immigration pattern, labor market integration rates have deteriorated and welfare dependency increased among immigrants."
To be frank, I'm not a fan of the phrase in the first place, and if anyone could help come up with a different choice of words, I will be grateful. Thx :)
