The experience of girlhood is shifting in Tanzania as family structure is altered by economic migration and the impact of HIV/AIDS. Also significant is the influence of globalization and global imagery, which are shaping the nature of girlhood and the experience of transitioning to young womanhood. A deeper understanding of how globalizing influences are changing girls' growing up experiences, from the perspectives of the girls themselves and the adults who intersect with them in their daily lives is essential. A rural versus urban comparative case study was conducted in the Kilimanjaro region of northern Tanzania, which explored the perspectives of girls and adults through a range of methodologies. Both adults and girls expressed concerns that globalization is negatively influencing the transition to young womanhood, with girls feeling much more appreciative of the new gendered opportunities provided by the influx of external influences.
