SPOTSWOOD, NJ - In honor of the 100th day of school, kindergarten students and their teachers at the Immaculate Conception School decided to find out what it would look like to be 100 years old.

Kids and adults donned glasses, wigs, hats and bow ties to dress up and mark the 100th day of school on Friday, Feb. 10. From canes to gray hair, youngsters aged gracefully to enjoy some fun on the first three digit milestone day of the school year.

So, how many people actually live to see their 100 birthday? Centenarians, people who are 100 years of age or older, do not make up a large portion of the population though their numbers are on the rise. According to US census data, there were 32,194 centenarians in 1980 and 53,364 in 2010. More centenarians also tend to be female.

Adele Dunlap, a Garden State gal, was the oldest American for the last six months. Dunlap became the oldest living US resident in July of 2016 after the passing of Goldie Michelson of Worcester, Mass. Michelson was 113 when she died. Dunlap, who was born in 1902 in Newark, recently passed the oldest American torch on to Delphine Gibson. Last week, Dunlap reportedly died at the age of 114 in a hospital outside of Flemington. The former teacher had three children. Gibson, who is 113 and resides in Huntingdon County, Pa., is now the oldest living American.
