The study of the situation of Thai disabled women (Torsangrasmee Teetakaew, 2021) has an interesting data that shows the increasing number of disabled women during the next 20 years. This is a big challenge for the preparation of the quality of life for the disabled women living through the aging society. The objectives of this research are to estimate the number of disabled women in Thailand over the next 20 years and analyze the situation by using a sample questionnaire of 2,300 disabled Thai women from 30 provinces as well as from in-depth interviews from 10 leaders of disabled women in various activities. The results of the study showed that the number of women with disabilities will increase from approximately 990,419 in 2021 to 1,014,015 over the next 20 years, which is a 1.95% increasing rate annually. The increasing rate of disabled women aged 60 years and above is 3.62% per year. In contrast, the percentage of younger age group will be increasing gradually at 1.44%, 1.14 %, 1.17 %, and 0.85 % for age group 0-5, 6-14, 15-21, and 22-59 years old accordingly. When classified by the type of disabilities, it was found that the number of women with disabilities increases across all types. There is an increase of approximately 1.78 - 3.01% per year for intellectual disability, learning disability, and visual disability.
