Nationalism usually works on the basis that a nation should imagine itself as a “we”, with a common identity, history and culture. But it doesn’t always clearly say who the “we” are. Instead, it often works by saying who doesn’t belong – frequently by characterising these people in racialised ways.

Singapore is an interesting case study. Since independence in 1965, the small city-state has explicitly committed to a policy of multiracialism and multiculturalism. This principle is enshrined in its constitution, is widely accepted by Singaporeans and has become a firm pillar of national discourse.

Given this commitment, how does nationalism create exclusion in Singapore and what other forms could this take? In my March 2025 book, Straight Nation, I analyse Singapore’s version of a national identity to show how, while avoiding overtly racialised rhetoric and discrimination, it can define belonging in other ways.

Singaporean nationalism excludes some sections of society mainly through maintaining a set of heterosexual familial norms. This is one reason for the book’s title – it calls attention to how straightness sits at the heart of Singaporean identity. A certain kind of straight life is taken to be the model behaviour of a “normal” citizen.

Some of the things one is expected to do include starting a family – by meeting a member of the opposite sex, getting married and having children. This very specific version of heterosexuality is taken as the default in Singapore, and it ends up excluding a whole range of people.

Family and the nation

Heterosexuality being taken as normal and the expectations placed on the nuclear family are not uniquely Singaporean issues. But because of Singapore’s small size, the state has an outsize capacity to influence both how the “normal” Singaporean ought to live and the consequences that follow.

One of the most visible ways people are affected is through the public housing system. Almost 80% of Singaporean residents live in flats built by the country’s public housing authority, the Housing and Development Board (HDB). These flats are so ubiquitous that Singapore’s former prime minister, Lee Hsien Loong, referred to them as “national housing” in 2018.

The catch is that, with some small exceptions, one has to be married to buy a HDB flat. And because same-sex marriage is not recognised in Singapore, heterosexual marriage becomes a condition of access to this national symbol.

This obviously affects LGBTQ+ people, limiting their ability to access public housing and live independently. But the link between heterosexual marriage and public housing affects a whole range of other people. These include single people and parents, those who choose not to get married and people who are divorced.

There are other examples that demonstrate how it is taken as common sense that one’s life revolves around the nuclear family in Singapore – even though this might not be the case for everyone.

The opening anecdote in Straight Nation shows how the state treats the heterosexual nuclear family as containing the most important set of social relations. Like many other countries at the height of the COVID-19 pandemic, the Singaporean government imposed a lockdown from April to June 2020. When it ended, restrictions were lifted in stages.

Initially, only some in-person interactions were allowed. Singapore’s then-health minister and current deputy prime minister, Gan Kim Yong, said: “Children or grandchildren can visit their parents or grandparents”. He suggested this would “allow families to spend time and provide support to one another” after eight weeks of isolation.

Until the restrictions were further eased 17 days later, visiting one’s parents or grandparents was the only form of in-person social interaction permitted. There was no mention as to what people without a family or estranged from them were meant to do for support. The same applies to people reliant on extended family, such as those who have no have no surviving parents or grandparents, or even those who depend on a close friend.

Again, this assumption can produce exclusions that go beyond sexual difference. To be clear, not everyone will be affected in the same way. But reading Singapore as a straight nation and identifying how one particular kind of heterosexual expression is reified is helpful.

It allows onlookers to ask how these norms can place different kinds of pressure on different people. And perhaps identifying the way in which so many people are affected by this regime of straightness will also help Singapore imagine a future that is fairer and more liveable for everyone.
