A careful projection of Down syndrome prevalence through the year 2100 requires expert elicitation of determinative factors, These findings come from The National Down Syndrome Cytogenetic Register, which has gathered data on the number of Down’s diagnoses and births since 1989. The register’s data shows that overall diagnosis of the condition has risen by 71% over the past 20 years, from 1,075 in 1989 to 1,843 in 2008.
