History of the Welsh language
Denbighshire was the only other county where a majority could still speak Welsh, here, 51.0% could speak Welsh and 94.0% could speak English. As for larger urban areas, Aberdare was the only one where a majority could still speak Welsh, here 59.0% could speak Welsh while 95.4% could speak English. In Cardiff, Wales' capital, 5.2% of people could speak Welsh, while 99.7% of people could speak English. 
At a district level, Llanfyrnach rural district in Pembrokeshire had the highest percentage of Welsh speakers; at 97.5%, while Penllyn rural district in Merioneth had the highest percentage of Welsh monoglots; at 57.3%. Bethesda urban district in Carnarvonshire was the most Welsh speaking urban district in Wales; 96.6% of the district's population could speak Welsh.
Immigration to Denmark
Another explanation relates to the structure of the Danish labor market, which consists primarily of highly skilled jobs with firm-specific training and few low skill or entry level positions. In addition, many entry level jobs require vocational training which most immigrants lack. Denmark's labor market is also characterized as flexible, with high levels of employee turn over. Immigrants' lack of language skills and cultural knowledge have been argued to be linked to their shorter periods of employment and lengthier dependency on unemployment benefits. The length of time an immigrant has lived in Denmark, their Danish language skills, and their associations with native Danes have been identified as being positively linked to immigrant employment. The connection between the gender of immigrants and these as well as additional factors, such as parenthood, and the level of Danish language skills, and the importance of education and employment qualifications differ among male and female immigrants. One study found that men’s language skills and qualifications were of less importance than for women immigrants applying for jobs. It was also found that immigrant women with small children were less likely to be employed than those without.
