Yeah, not sure where you are looking, but it's wrong. From NILC (National Immigration Law Center).
Who is eligible for an initial grant of DACA?
To be eligible for deferred action under the DACA program, you must:
- Have come to the United States before your sixteenth birthday.
- Have lived continuously in the U.S. since June 15, 2007.
- Have been present in the U.S. on June 15, 2012, and on every day since August 15, 2012.
- Not have a lawful immigration status on June 15, 2012. To meet this requirement, (1) you must have entered the U.S. without papers before June 15, 2012, or, if you entered lawfully, your lawful immigration status must have expired before June 15, 2012; and (2) you must not have a lawful immigration status at the time you apply for DACA.
- Be at least 15 years old at the time you apply for DACA.
- Have graduated or obtained a certificate of completion from high school, have obtained a general education development (GED) certificate, be an honorably discharged veteran of the Coast Guard or U.S. armed forces, or “be in school” on the date you submit your DACA application. See below for more information about meeting the “be in school” requirement.
- Have not been convicted of a felony offense. A felony is a federal, state, or local criminal offense punishable by imprisonment for a term exceeding one year.
- Have not been convicted of a significant misdemeanor offense or three or more misdemeanor offenses. See below for more information about offenses that may disqualify you.
- Not pose a threat to national security or public safety. DHS has not defined precisely what these terms mean but has indicated that they include gang membership, participation in criminal activities, or participation in activities that threaten the U.S.
Th reason they didn't include under 16 is simple.
They have to be at least 15 years old before they can apply, and with most programs involving the government, it's a very tedious, drawn out and slow moving process. It often takes months/years for approval, meaning most applicants have already turned 16+ by the time they're actually approved as a recipient.
Those who are lucky and get approved more quickly, while still being 15 years of age, make up a very, very small percentage of the recipients. Moreover, under 16 recipients are so miniscule they barely affect the percentages, so much so, they are irrelevant to the point of the chart.
