As of the year 2019, Astronism has more than 3.5 million adherents worldwide, out of a global total population of 7.5 billion people. Astronists represent a very small proportion of the global population proportionally 0.04%. The principal significant denomination representing Astronists is the Astronist Institution, which was conferred proprietorship over Astronism by Cometan as the founder of Astronism during his authorship of the Omnidoxy.

The study of the demographics of Astronists by Astronist and non-Astronist scholarship began just six years following the religion's official founding in 2013. Since then, an entire discipline has developed to deal with the study of Astronist populations on a global level, the concentrations and dispersions of such populations, and the differences in beliefs and practices between populations of Astronists. This discipline is known as geoastronology or astrogenology.

Astronism by country refers to the study of the demography of Astronism according to independent and dependent territories. From its inception, although Astronism may manifest itself in the form of being an ethnic tradition, or become interpreted in this way, it has and remains a universal tradition.

This means that one of its sole intentions is to spread to as many adherents as possible which is also a characteristic of its categorisation as an organised philosophy. The study of the way in which Astronism has been disseminated in a historically is referred to as disseminology, branches of which include tiritology and promulgative theory.

The nature of the organisation, functions, and depictions of Astronism in a society is therefore solely left to the governing body of The Institution with additional guidance sought from the Omnidoxy and from Astronist scholarship.

Like all major traditions of thought, the diversity of the tradition is as varied as the people that adhere to it or as diverse as the countries in which it holds a presence. With the intention of monitoring the expansion of Astronism and understanding how its growth occurs across different countries through various periods, the study of philosophical demographics as a branch of geoastronology was introduced by Cometan in the Omnidoxy.

Astronism is currently not recognised by any sovereign power as a religion in their respective country and as a direct result, repression and persecution of Astronists has occurred since the religion's founding. The fact of Astronism's lack of recognition has also made it difficult to obtain accurate estimates on the number of Astronists per country, although the Astronist Institution continues to develop its methods in an attempt to retrieve more reliable data on Astronist demographic statistics.

This page includes statistics of those whom identify as Astronist on the assumption that the word Astronist is synonymous with being a follower of the form of Astronism espoused by the Astronist Institution. From its inception, Astronism has existed in a digital form in the majority of countries worldwide which lead the way on the awareness of its beliefs and practices to a global level.

Studied by disseminologists, this phenomenon in which Astronism was instantly global from its inception and was forced to deal with such a vast global presence from its earliest days demonstrated a significant difference from how other more ancient and premodern religions disseminated themselves. As a direct result of this, unlike other religions, Astronism has held a presence in every country since its founding years and the numbers of Astronists per country reflect this plateau of populations rather than concentrated masses.

From these results below, the countries with the highest proportions of Astronists include China, India, United States, United Kingdom, Brazil, Nigeria, the Philippines, Indonesia, Russia, Mexico, Canada, France, Germany, and Democratic Republic of the Congo.

Astronism is represented by the presence of the Astronist Institution, but Astronism is part of a wider tradition or collection of religions, namely the Astronic religions. This wider tradition of religions are represented by a network of Astronic Federations of which the Astronist Institution and other organisations are members.

Methodology

The figures produced as part of this study have been gathered by the Astronist Institution itself as part of their astrogenological department. The Demographics of Astronism report is produced and published yearly, usually in December following a month of data collection in November. According to the Astronist Institution, the five countires with the largest numbers Astronists are, in decreasing order of the Astronist population, China, India, United States, Nigeria, and the Philippines. The Astronist Institution began compiling data on Astronist populations on a yearly basis from 2019 (six years after the founding of Astronism), specifically every November.

Statistics from the Astronist Institution regarding Astronist populations are collected according to estimates on those whom self-identify as Astronists. The Astronist Institution collects the numbers of Astronists nominally and transfers these numbers across to the proportion of Astronists per country.

The Astronist Institution represents the body of Astronist scholarship and non-Astronist scholarship on Astronist demography is represented by other organisations that are not Astronist in leaning.

Conflicting figures on the population of Astronists have existed since demographical records began in 2019, six years after the founding of Astronism. Such conflicting figures are largely different between Astronist scholarship and non-Astronist scholarship. However, due to the fluctuating nature of demographic statistics, the number of Astronists or religious populations otherwise are very difficult to continue to measure and maintain.

The study of Astronist populations are split according to independent territories, dependent territories, as well as regional and continental areas with an apolitical approach, usually in alignment with the United Nations considerations regarding which countries can be considered independent or otherwise based on general consensus of the status of certain territories.

Keeping neutral in the study of demographics of Astronists is important to the maintenance of the integrity of the Astronist Institution. However, the Astronist Institution has a tendency to reorient itself on the reactions of nations towards Astronism and the way in which Astronists are treated by the governments of different countries.

Essentially, the Astronist Institution takes a stance of neutrality initially and in reaction to the actions of other parties, may present political stances on the status of particular countries. Maps depicting the populations of Astronists are always provided in tones of purple as purple is one of the principal colours representing the Astronist Institution.
