The total fertility rate (TFR) is a point in time estimate of the number of children that the average woman has over a lifetime, compiled from a population weighted average of the number of children born to women of each age.
The "coupling rate" is the percentage of adults who are married to, or cohabit out of marriage with, a partner.
The strong implication of this data is that in the last thirty years, in developing and developed countries, declining rates of child bearing are mostly a product of declining rates of couples living together (whether or not they are married), rather than being mostly due to couples having children at a much lower rate due to wider use of contraception (which probably is the biggest factor in undeveloped countries).
