The global prevalence of single-child families with emphasis on influential factors: a comprehensive systematic review and meta-analysis.
Synthesis in Population health metrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSingle-child families represent an expanded phenomenon in recent years due to prevailing socio-economic challenges. The single childbirth phenomenon can potentially cause negative population growth and undesirable effects on families. Thus, this study aimed to determine the prevalence (percent) of single-child families with an emphasis on interfering associated factors.
methodsFor paper collection, valid databases of PubMed, Embase, ScienceDirect, Web of Science, Scopus, and Google Scholar search engine were systematically searched. All relevant studies were transferred to EndNote software (v.8) for duplicate detection. Primary and secondary screenings were applied and eligible studies enrolled for meta-analysis (CMA v.2). In this regard, the random effect model was employed and the I² index was used for heterogeneity assessment.
resultsFollowing the examination of 33 studies, the prevalence (percent) of single-child families was found 41.3% (95% CI:33.1-49.9%). Meta-regression analysis revealed that following the acceleration in sample size and year of paper publication, the prevalence (percent) of single-child family increases and decreases (p < 0.05). Additionally, various influential factors effective on single-child families were listed as income status, financial difficulties, religious beliefs, educational level, and employment status.
conclusionAccording to the relatively high prevalence (percent) of single-child families and the influential impacts on families and communities, the findings of this study can provide valuable insights for policymakers to design appropriate policies and achieve demographic balance.
