Membership in the ruling party tends to be relatively small compared to the population.[3] With such a small winning coalition, leaders in one-party states usually lack the incentive to care about the well-being of citizens. Rather, they give out private goods to fellow elites to ensure continued support. One-party, compared to dominant-party dictatorships, structure themselves unlike democracies. They also turn into democracies at a lower rate than dominant-party dictatorships.[4] While one-party states prohibit opposition parties, some allow for elections at the smallest local level. One-party states lack any legitimate competition. Therefore, they place elites and sympathetic candidates in key administrative races.[5] For example, the Chinese Communist Party exercises political control by infiltrating village administrations.[6] They view these positions as crucial for gathering information on the population and maintaining a presence in the far reaches of their borders.[7]
One-party states recognize the trade-off between election victory and gathering valuable data.[8] To account for this, the regimes have been observed placing local nobility in easy-to-win races.[9] One-party states have also been observed using elections to ensure that only the most popular elites get chosen to office.[10] They also gather data from elections to indicate if a local official is performing poorly in the eyes of the residents. This gives locals the opportunity to monitor local officials and communicate satisfaction with the local government. Throughout the country, members of the one party hold key political positions. In doing so, the party avoids committing outright fraud and rather sustains their power at the local level with strategic appointment of elites. Data on one-party regimes can be difficult to gather given their lack of transparency.
