How many children died in 911?

Eight children were killed in the 9/11 attacks. All were passengers on the hijacked planes (none were known to have died in the buildings- there was a daycare center in one of the twin towers but it was on a lower floor so all of the children were evacuated safely). According to all of the memorials and lists of victims, these are the children who lost their lives that day:
