I'm confused, where does the 2.1% come from. It does look like 0.001795 which is 0.2% for a 30 year old in the source you linked

.001795 for year 30 = .998205 survival this year

.001858 for year 31 = .998142

...

.002482 for year 39 = .997518

---------------------

.998205 x .998142 x ... x .997518 = .978997 survival rate over 10 years

1 - .978997 = .021003 chance of death = 2.1%

The number you read is for dying within the next year. The OP said within a decade.

OP also said "in their 30s" not "at 30". So I'd use 35-45 rather than 30-40, which shifts it a bit.

Since I already have the spreadsheet built for my other comment:

30-39 is 2.1%

35-44 is 2.5%

40-49 is 3.3%

---------

30-49 is 5.3%

Ranges are inclusive of entire year. 30-39 is 30th bday to 40th bday
