MANILA - Who are the so-called millennials?

It turns out that if you are born between 1981 and 1996, you are a millennial, according to U.S. think tank Pew Research Center.

"Pew Research Center has been studying the Millennial generation for more than a decade. But as we enter 2018, it’s become clear to us that it’s time to determine a cut-off point between Millennials and the next generation," Pew Research Center president Michael Dimock said on their website.

"Turning 37 this year, the oldest Millennials are well into adulthood, and they first entered adulthood before today’s youngest adults were born."

Dimock said that generational cutoff points are not "exact science" and should be "viewed primarily as tools."

"Generations are often considered by their span, but again there is no agreed upon formula for how long that span should be. At 16 years (1981 to 1996), our working definition of Millennials will be equivalent in age span to their preceding generation, Generation X (born between 1965 and 1980)," he said.

"By this definition, both are shorter than the span of the Baby Boomers (19 years) – the only generation officially designated by the U.S. Census Bureau, based on the famous surge in post-WWII births in 1946 and a significant decline in birthrates after 1964."

Dimock said the think tank has not yet decided on what to call the generation succeeding the millennials.

"Since the oldest among this rising generation are just turning 21 this year, and most are still in their teens, we think it’s too early to give them a name...and we look forward to watching as conversations among researchers, the media and the public help a name for this generation take shape. In the meantime, we will simply call them 'post-Millennials' until a common nomenclature takes hold," he said.
