Do young people in Europe and America use English names Liz or kirsten more now? Which name is good? Thank you~

To be honest, LIZ is just a nickname, not a very formal feeling. Elizabeth is usually written on a person's ID, which is a typical English name. In fact, in a big immigrant country headed by the United States, there are many foreign names, such as HANNA is a typical German name and KRISTEN is a Nordic name. Personally, Elizabeth is better. You can introduce yourself, my name is Elizabeth, but my friends always call me Meredith.
