1) born in or after 2030
2) born in 2030 or later
Are these correct?
People with good genes, born in or around 2030, will have a good chance of living until 2100.
I'm not sure which country this refers to. In the UK, living until the age of 70 is not at all unusual. The average life expectancy in the UK, for people born between 2013 and 2015, is 79.1 years for men and 82.8 years for women.
