Desecularization is the process by which religion reasserts its societal influence though religious values, institutions, sectors of society and symbols in reaction to previous and/or co-occurring secularization processes.
Scholars of religious demographics frequently use the term the "global resurgence of religion" to describe the process of global desecularization which began in the late portion of the 20th century.
On December 23, 2012, Professor Eric Kaufmann, who teaches at Birbeck College, University of London, wrote:
|“|| I argue that 97% of the world's population growth is taking place in the developing world, where 95% of people are religious.
On the other hand, the secular West and East Asia has very low fertility and a rapidly aging population... In the coming decades, the developed world's demand for workers to pay its pensions and work in its service sector will soar alongside the booming supply of young people in the third world. Ergo, we can expect significant immigration to the secular West which will import religious revival on the back of ethnic change. In addition, those with religious beliefs tend to have higher birth rates than the secular population, with fundamentalists having far larger families. The epicentre of these trends will be in immigration gateway cities like New York (a third white), Amsterdam (half Dutch), Los Angeles (28% white), and London, 45% white British. 
Religious are expected to see a net gain in political power in the 21st century

The Brookings Institution, one of America's oldest think tanks, indicates:
|“||There was a belief for centuries that modernization meant westernization and secularization. As Rabbi Sacks described, the 17th through 20th centuries were witness to the secularization of knowledge, power, culture, and morality. However, this secularization is not sustainable. According to Rabbi Sacks, the 21st century will be more religious than the 20th, even if not one religious believer persuades any skeptic, because “the more intensely you believe religiously, the more children you have.”||”|
A Christian Post in an article entitled Rabbi Jonathan Sacks: Secularism Can't Solve Today's Religious Violence; Answers Rooted in 'Sibling Rivalry' of Jews, Christians, Muslims:
|“||But those 17th century ideas will not work in the 21st century, Sacks continued, because, "the 17th century was the beginning of an age of secularization which has lasted four centuries until now; the 21st century is exactly the opposite, it's the beginning of an age of desecularization. Religion is seizing power; they're not yielding power. ... We are going to have to do the theological work that was not done four centuries ago."||”|
American culture war, demographics and expected tipping point after 2020
Eric Kaufman wrote in his 2010 book Shall the Righteous Inherit the Earth? concerning America:
|“||High evangelical fertility rates more than compensated for losses to liberal Protestant sects during the twentieth century. In recent decades, white secularism has surged, but Latino and Asian religious immigration has taken up the slack, keeping secularism at bay. Across denominations, the fertility advantage of religious fundamentalists of all colours is significant and growing. After 2020, their demographic weight will begin to tip the balance in the culture wars towards the conservative side, ramping up pressure on hot-button issues such as abortion. By the end of the century, three quarters of America may be pro-life. Their activism will leap over the borders of the 'Redeemer Nation' to evangelize the world. Already, the rise of the World Congress of Families has launched a global religious right, its arms stretching across the bloody lines of the War on Terror to embrace the entire Abrahamic family.||”|
Secular left's inability to stop the rise of anti-homosexuality laws around the world
See also: Decline of the secular left
The conservative journalist Peter LaBarbera of Americans for Truth wrote: "Anyone who has researched the subject of homosexuality knows that many of the most staunch advocates of homosexuality are those who hold a decidedly secular outlook." (See also: Atheism and homosexuality).
In February 2014, Newsweek reported a rise of anti-homosexuality laws around the world.
Secular leftism and anti-homosexuality
See also: Atheism and anti-homosexuality
Although not many contemporary secular leftists are aware, historically there have been notable cases of communist countries that have had a history of anti-homosexuality (see: Atheism and anti-homosexuality).
For example, in the atheistic communist state of the Union of Soviet Socialist Republics (USSR), "a person could end up in prison for being openly gay." This policy was enforced after 1934, and went hand in hand with the Soviet Union's official doctrine of militant atheism.
Although Chinese literature cites homosexual practice since ancient times as one that was fairly tolerated, after the Chinese Communist Party, which officially espouses atheism, came to power in 1949, homosexuality was deemed a sexual crime and then classified as an abnormal (buzhengchang) mental illness. Under the Great Proletarian Cultural Revolution, homosexuals experienced punishment that ranged from "labor under surveillance to imprisonment for years". Moreover, atheistic communist officials "when queried by foreign visitors, until recently simply denied that homosexuality existed in China".
Secular left unable to shut down the Quiverfull movement
The Quiverfull movement is an evangelical Christian movement which eschews all forms of birth control - including natural family planning. The left has been unable to shut down the Quiverfull movement.
Presently, several thousand Christians worldwide belong to this movement.
Berger's The Desecularization of the World: Resurgent Religion and World Politics
Peter L. Berger is an Austrian-born American sociologist best known for his work in the fields of the sociology of knowledge/religion, the study of modernization, and various theoretical contributions to sociology.
The Publisher's Weekly review of his 1999 book The Desecularization of the World: Resurgent Religion and World Politics declares:
|“||In the 1950s and 1960s, Berger, Harvey Cox and others were fearless proponents of "secularization theory." This theory held that as technology improved and modernity advanced upon culture, religion would begin to decline and we would live, according to Cox, in a "secular city." Cox reversed himself in Religion in the Secular City (1984), declaring that the future of religion lay in grassroots movements such as fundamentalism, Pentecostalism and liberation theology. Now, Berger gathers a number of essays contending that, far from being in decline in the modern world, religion is actually experiencing a resurgence. In his opening essay, Berger asserts that "the assumption we live in a secularized world is false.... The world today is as furiously religious as it ever was." He points out that religious movements have not adapted to secular culture in order to survive but have successfully developed their own identities and retained a focus on the supernatural in their beliefs and practices. Berger then examines the origins, and ponders the future, of this global religious resurgence. ...He also provides a brief overview of the impact of religion on economic development, war and peace, human rights and social justice. Other essayists contribute "Roman Catholicism in the Age of John Paul II" (George Weigel), "The Evangelical Protestant Upsurge and Its Political Implications" (David Martin), "Judaism and Politics in the Modern World" (Jonathan Sacks), "Europe: The Exception That Proves the Rule?" (Grace Davie), "The Quest for Meaning: Religion in the People's Republic of China" (Tu Weiming) and "Political Islam in National Politics and International Relations" (Abdullahi A. An-Na'im). Berger's collection is replete with compelling writing about the relationship of religion and politics.||”|
