Jeremy and his twin sister Jessica are both 22 (Born February 5,1989) as of 2011, Their younger sister, Jennifer (Also known as Gigi) is currently 21 (Born July 2,1990). They also have a younger brother, Travis (Which is currently in college, so he is probably 18 or 19, but I'm not sure when his birthday is or his exact age).
It could be possible he is 15 like Candace, but in the episode 'At the Car wash' he drives a car, so he could be older. But he did say that he was going to college soon in "Phineas And ferb Across The 2nd Dimension" and Candace said she was 1 year younger than Jeremy so he could be about in the 18's or 19's and Candace is like 17 or 16
Jeremy is 17, a year older than Candace. Candace said to Jeremy in an episode: "Wow, I forgot that you're a whole year older than me." Candace is 16, therefore, Jeremy is 17.
Jeremy is the same age as Candace they are both 16 years old.
Around eight or nine. Probably nine.
Jeremy is played by Mitchel Musso. Candace is played by Ashley Tisdale.
