MDI examined the issue of migration for Tuusula according to the structure and direction of the migration flows. The review consisted of two sections: an annual migration review and a monthly migration review. The annual review described migration within Tuusula by age group and region. The monthly review describes, more generally, migration and other demographic trends in accordance with the latest data. This review is updated on a monthly basis. The review increases the understanding of the monthly variation in Tuusula's migration and the role of different regions in Tuusula in internal migration. An examination of internal areas revealed differences in the attractiveness of different parts of the municipality in relation to different groups of migrants, as well as areas of particularly strong attractiveness in recent years.
