Why this matters
Understanding the languages around us helps us ask better questions about learning, communication and belonging. A regional count can show scale; school and community evidence can reveal needs that a single ranking cannot describe.

Home language is one part of the picture. It does not tell us every language someone knows, their first language or which language they prefer for services.
Three questions. A fuller picture.
At home
What languages do people use with family and household members?
Learning
What languages do people want to learn or practice?
Taking part
What helps people communicate at work and in community life?
Better questions help us design more welcoming learning opportunities, conversations and services.
