In developing economies savings clubs are a common alternative (or complement) to saving at a formal financial institution. One common form is the rotating savings and credit association (ROSCA)—known as a _susu_ in West Africa, an _arisan_ in Indonesia, and a _pandero_ in Peru. These clubs generally operate by pooling the weekly deposits of their members and disbursing the entire amount to a different member each week.

Community-based savings methods such as savings clubs are widely used in some parts of the world but most commonly in Sub-Saharan Africa (figure 2.4). In that region 19 percent of adults report having saved in the past year using a savings club or person outside the family. Among just those who report any savings activity in the past 12 months, 48 percent use community-based savings methods. The practice is particularly common in Nigeria, where ROSCAs are called _esusu, ajo, cha,_ or _adashi._ In that country 44 percent of adults (and 69 percent of those who save) report using a savings club or person outside the family. Perhaps because of the widespread use of this savings method, the share of Nigerians who report any type of saving in the past year is equal to that in Canada and the Republic of Korea and far higher than that in other developing economies.

The use of savings clubs in other regions, while less widespread than in SubSaharan Africa, is still substantial: in the Middle East and North Africa 18 percent of savers report having saved using a savings club in the past 12 months, in South Asia 16 percent, in Latin America and the Caribbean 15 percent, and in East Asia and the Pacific 11 percent.

Many people use both formal and community-based savings methods, especially in the developing world. In Sub-Saharan Africa 5 percent of adults (and 14 percent of savers) report having saved using both formal and community-based methods in the past year. Globally, slightly less than half of all adults who report having saved in the past 12 months using an informal savings club or person outside the family also report having saved using a formal financial institution.

While many savers in the developing world blend formal and informal methods, an even larger share use only community savings clubs. In Sub-Saharan Africa 34 percent of savers report having saved using a community savings club (and not a formal financial institution) in the past 12 months.

The popularity of savings clubs speaks to their advantages, but these arrangements also have downsides. Their essential characteristic—informality—is accompanied by risks of fraud and collapse (although formal accounts are not immune to these risks where explicit government-run deposit insurance is absent or inadequate, as it is in many developing economies). In addition, the cyclical nature of contributions and disbursements can be too rigid for some people and out of sync with their needs to deposit surplus income or quickly withdraw funds for an emergency.

Community-based savings methods and formal financial institutions are not the only options for saving. A large share of adults around the world who report having saved or set aside money in the past 12 months do not report having done so using a formal financial institution, informal savings club, or person outside the family.
