birth rate is usually defined as number of birth per 1000 person per year.
1.23 = 1.23 babies/1000 person per year.
surely the paper make this sound so scary. we got 5m ppl 1.23 = abt 6k babies last year...
i dig a little being a bloody nerd and took 4 years of stats education tells me that half the time the paper are just making is so scary.
truth is 1.23 refers total fertility rate per female. meaning they count all the ah ma and xmm that cant give birth.
in 2008 there was 39k birth. actual birth rate is actually around 7.8 than 1.23 -_-.
however we should note that countries like china have 22-30 birth rate.
