Demographics of France
France has been influenced by the different human migrations that occurred throughout Europe over time. Prehistoric and Neolithic population movements could have influenced the genetic diversity of this country. A recent study in 2009 analysed 555 French individuals from 7 different regions in mainland France and found the following Y-DNA Haplogroups. The five main haplogroups are R1 (63.41%), E (11.41%), I (8.88%), J (7.97%) and G (5.16%). R1b (particularly R1b1b2) was found to be the most dominant Y chromosomal lineage in France, covering about 60% of the Y chromosomal lineages. The high frequency of this haplogroup is typical in all West European populations. Haplogroups I and G are also characteristic markers for many different West European populations. Haplogroups J and E1b1b (M35, M78, M81 and M34) consist of lineages with differential distribution within Middle East, North Africa and Europe. Only adults with French surnames were analyzed by the study.
