Abstract
This paper presents approximate estimates of the size, growth, and changing demographic characteristics of Australia's lesbian, gay, and bisexual (LGB+) population. We used weighted data from a longitudinal panel survey at three time points to estimate the population by sex and age group in 2012, 2016, and 2020, and we applied cohort analysis to help understand the drivers of its growth. The LGB+ population aged 15 and above doubled in size over the eight-year period, increasing from 0.58 million in 2012 to 1.18 million in 2020. More men than women identified as LGB+ in 2012, but this had reversed by 2016. Our estimates show that the LGB+ population is young and becoming younger over time, with cohort analysis showing that its growth has been driven primarily by recent cohorts of young women with a bisexual identity. We discuss what might be driving this growth and whether our results suggest continued rapid LGB+ population growth in future.
期刊介绍：
For over half a century, Population Studies has reported significant advances in methods of demographic analysis, conceptual and mathematical theories of demographic dynamics and behaviour, and the use of these theories and methods to extend scientific knowledge and to inform policy and practice. The Journal"s coverage of this field is comprehensive: applications in developed and developing countries; historical and contemporary studies; quantitative and qualitative studies; analytical essays and reviews. The subjects of papers range from classical concerns, such as the determinants and consequences of population change, to such topics as family demography and evolutionary and genetic influences on demographic behaviour.
