Various developmental disabilities are simply categorized by the administration.
There are also many people who do not fit the criteria, but are considered to possibly develop those disabilities in the future.
Whether they fit the society or not is how the administration sets their standards.
ご質問ありがとうございます。
"Various developmental disabilities are simply categorized by the administration."＝「様々な発達障害は行政の単なる区分である。」
"There are also many people who do not fit the criteria,"＝「条件に該当しない人も多い」
"but are considered to possibly develop those disabilities in the future."＝「でも将来、それらの障害を発症するかもしれないとされている。」
"Whether they fit the society or not is how the administration sets their standards."＝「彼らが社会に適合するかどうかが行政の判断基準である。」
