Read the Passage given below and answer the questions:
Most demographic concepts are expressed as rates or ratios – they involve two numbers. One of these numbers is the particular statistic that has been calculated for a specific geographical-administrative unit; the other number provides a standard for comparison. For example, the birth rate is the total number of live births in a particular area (an entire country, a state, a district or other territorial unit) during a specified period (usually a year) divided by the total population of that area in thousands. In other words, the birth rate is the number of live births per 1000 population. The death rate is a similar statistic, expressed as the number of deaths in a given area during a given time per 1000 population. These statistics depend on the reporting of births and deaths by the families in which they occur.

What do you mean by maternal mortality rate?

number of women who die in childbirth per 1,00,000 live births.

The correct answer is Option 2: number of women who die in childbirth per 1,00,000 live births.

NCERT: "The infant mortality rate is the number of deaths of babies before the age of one year per 1000 live births. Likewise, the maternal mortality rate is the number of women who die in childbirth per 1,00,000 live births. High rates of infant and maternal mortality are an unambiguous indicator of backwardness and poverty; development is accompanied by sharp falls in these rates as medical facilities and levels of education, awareness and prosperity increase. One concept which is somewhat complicated is that of life expectancy. This refers to the estimated number of years that an average person is expected to survive. It is calculated on the basis of data on age-specific death rates in a given area over a period of time.".
