Crude birth rate (cbr) 🍼
- Definition: Number of live births for every 1000 people in a population.
- Example: In 2018, China had 15.23 million babies. With a population of 1,415 million, their CBR is 10.94‰ (almost 11 babies for every 1000 people). 🇨🇳👶
- But, keep in mind! CBR doesn't consider age or gender. So, it’s a bit like judging a book by its cover.

Population mortality & crude death rate (cdr) 💀
- Definition: Number of deaths per 1000 people in a population.
- Formula: CDR = (Total deaths / Total population) x 1000
- Example: China saw 9.93 million people pass away in 2018. This gives them a CDR of 7.13‰.
- Hmm...But: CDR isn't the best to check mortality trends. Why? Countries with more grandparents 👵🧓 (like many MEDCs) will naturally have a higher CDR than those with more kiddos.
Total fertility rate (tfr) 👩👧👦
- Definition: The average number of babies a woman might have during her childbearing years.
- Example: In 2018, for every 100 women in China, there were 160 kids born. So, the TFR in China was 1.6.
- Did you know? The poorest countries often have the highest fertility rates. Meanwhile, MEDCs, like some European countries, see fewer babies per woman. It’s like comparing a crowded daycare to a quiet library. 📚
