The year of birth interval refers to a range of years during which individuals are born, often used in demographic studies to categorize populations or analyze trends. This interval helps researchers understand patterns in birth rates, generational characteristics, and societal changes over time. It can also facilitate comparisons between different cohorts, such as Millennials or Generation Z, highlighting the unique experiences and influences that shape these groups. Overall, it provides a framework for studying population dynamics and their implications.
The shortest interval on record between the birth of two children is just 23 days. This remarkable feat was achieved by a woman in the United Kingdom in 2012, who gave birth to her first child on September 12 and then to her second child on October 5 of the same year. Such a short interval is highly unusual and poses significant health risks for both the mother and the newborns.
It is an interval scale. It is not a ratio scale, the next higher level, because the zero is arbitrary and not unique from one calendar to another.

Date of birth is considered a ratio variable, not ordinal or interval. While it can indicate order (when someone was born before or after another), it also has a true zero point (the start of the calendar) and allows for meaningful comparisons of differences in age. This distinguishes it from ordinal (which only indicates order) and interval (which lacks a true zero) scales.
The longest documented time interval between the birth of twins is 87 days. This unusual case occurred in 2012 when a woman in Ireland gave birth to one twin prematurely, and the second twin was delivered nearly three months later. Such extended intervals are extremely rare and typically involve medical intervention to prolong the pregnancy of the second twin.
Year of birth is interval level of measurement; age is ratio.
The interval between each kitten birth is typically around 15-30 minutes.

The typical interval between the birth of kittens in a litter is usually around 15-30 minutes.

Without referring to twins, Jayne Bleackley is the mother who holds the record for the shortest interval between two children. She gave birth to Joseph Robert on September 3rd, 1999, and Annie Jessica Joyce on March 30th, 2000. The babies were born 208 days apart.

Yes it is possible although really its only one birth but with a large interval
