I don't think so. The fertility rate of a population is the average number of children that would be born to a woman over her lifetime if she were to survive from birth through the end of her reproductive life, whereas the birth rate is the rate of births in a population over time.

yeah, birth rate is generally expressed per year, it's a measure of how fast population is increasing (or conceivably dcreasing, but it usually doesn't). Fertility rate isn't. So, no, you can't use them interchangably.

@Loh Jane,

Pay no attention to contrex, she is either a troll or very sadly mistaken.

Yes, they are interchangeable, try googling define fertility rate.

no, they aren't interchangeable. See contrex's definition.

@oolongteasup,

I was ogling and came across the definition of fertility rate to be births per 1000 women and the definition of birth rate to be the number of live births per thousand of population per year. Interchangeable, these terms are not. Wrong, you are.

that's not the definition of fertility rate, which is basically the average number of live births a woman of a given area would have over the course of a lifetime, i.e. from puberty to menopause (that's kind of a simplified definition, there are a fair number of qualifiers to it as a technical term). As contrex said.

@MontereyJack,

It's a general definition, I've provided the link for an in depth explanations.

@Loh Jane,

Who told you that? Won't that depend on the sociological perspective that you're exploring and wanting to study?
The difference between birth rate and fertility rate is that birth rate is a parameter of the entire population, while fertility rate is a parameter of a group of individuals in the population. Fertility rate determines the birth rate, and not vice versa. Represented in relation to a time interval is the birth rate, while fertility rate is represented in relation to the number of females in the reproductive age.

Did you have a specific reason for insulting me, other than spite? Possibly you are the troll. I see your answer is laughably short of details.

Total fertility rate

From Wikipedia, the free encyclopedia

Not to be confused with birth rate.

The total fertility rate (TFR), sometimes also called the fertility rate, period total fertility rate (PTFR) or total period fertility rate (TPFR) of a population is the average number of children that would be born to a woman over her lifetime if she were to experience the exact current age-specific fertility rates (ASFRs) through her lifetime, and she were to survive from birth through the end of her reproductive life.

It is obtained by summing the single-year age-specific rates at a given time.

Birth rate

From Wikipedia, the free encyclopedia

Not to be confused with Total fertility rate.

The birth rate is typically the rate of births in a population over time.
The rate of births in a population is calculated in several ways: live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques. The birth rate (along with mortality and migration rate) are used to calculate population growth.

The crude birth rate is the number of births per 1,000 people per year.
Another term used interchangeably with birth rate is natality. When the crude death rate is subtracted from the crude birth rate, the result is the rate of natural increase (RNI). This is equal to the rate of population change (excluding migration).
