“If your experiment needs a statistician, you need a better experiment.”― Ernest Rutherford

As a scientific discipline, Vital Statistics is a subfield of demography and the study & research of characteristics of the civilized population. The term “vital statistics'' is deployed to the individual determination of some vital events.

The birth rate is an example of vital statistics and an investigation of trends in birth rates is an example of an application in the domain of vital statistics. There are various examples of vital statistics such as death rates, or the number of marriages, human population, etc.

While reading this article, you will learn the meaning of vital statistics, types and uses of vital statistics, and a brief note over vital statistics system

## Defining Statistics

Statistics, an agglomeration of numerical data, or simply the mathematical science that deals with the assortment, examining, and interpretation of numerical data through the use of the statistical theory of probability, specifically the tools and techniques that drive inferences regarding the features of the population via deciphering a random sample.

Here, Probability is a mathematical tool that is deployed in order to discuss uncertain events and plays an essential role in statistics.

Statistics is an interdisciplinary field; research and analysis in statistics have diverse applications in all scientific fields and research. Two essential concepts in the field of statistics are uncertainty and variation.

For example, various conditions are there in science where the outcome is uncertain. And statisticians try to understand and control, whenever possible, the origin of variation under any situation. Some statistical measures include mean, regression analysis, skewness, kurtosis, variance, and analysis of variance.

Additionally, statistics and its types are implemented in several disciplines like psychology, business, social science, humanities, government and manufacturing. Statistical data is collected through a simple procedure or various methods.

There are two types of statistical methods used in statistical data analysis:

• Descriptive Statistics: that are used to evaluate data from a sample practising the mean or standard deviation, and
• Inferential Statistics: that is implemented when the statistical data is reviewed as a part of a specific population.

## Vital Statistics

According to N.B. Ryder, vital statistics “give cumulative summaries for successive time periods of population movements like birth, death, migration, marriage and marital dissolution as well as demographic and other relevant characteristics of the individuals involved in these events.

In simple words, Vital statistics, or vital events or vital records as they are known generally, have become an important resource for demographic data. It explicates statistical events such as births, deaths, marriages, divorces, etc.

Vital statistics involves:

• Quantities and rates of births,

• Important characteristics of births, such as births by sex, location and maternal age,

• Quantities and rates of deaths, and

• Deaths by essential characteristics such as age, sex, location and cause of death.

Vital statistics are the statistical yield under the civil registration system, and the information, involved within the individual civil registration records, is assembled in order to create vital statistics for the population.

Some of the advantages are discussed below;

1. Constantly produced, as and when the events take place, and hence optimizing accurateness.

2. Accessible in an appropriate and convenient way over time and across geographics.

But I had no other choice than to contact him at drgaligaherbalcenter@gmail.com after everything was done, my husband came home. He was so sorry for all that happened. I'm sharing my experience with others who are going through marriage or relationship problems to seek help from the right place. drgaligaherbalcenter@gmail.com
