Birth Order and How Australian Kids Spend Their Time: A Deep Dive into Screen Time and Enrichment
The order in which children arrive in a family can have a surprising impact on their lives, extending beyond just parental attention or perceived privileges. Emerging research suggests that firstborn children, on average, tend to achieve better outcomes across various metrics, including academic performance and leadership roles later in life. Building on this, a recent study has delved into how birth order might influence the way children, both independently and with their parents, allocate their time. The findings reveal notable differences in screen usage and engagement with activities that foster intellectual development.
The Study: Unpacking Australian Children's Daily Lives
This comprehensive study drew upon survey data from approximately 5,500 Australian children, aged between two and 15 years. The data originates from the Longitudinal Study of Australian Children, a nationally representative survey designed to capture detailed insights into the lives of young Australians.
Central to the research were 24-hour diaries meticulously completed by the children. These diaries provided a granular record of how each child spent their time from the moment they woke up until they went to sleep. Crucially, the diaries also specified whether activities were undertaken with parents or independently.
The researchers then categorised these recorded activities into five key areas: * Sleep: Time dedicated to rest. * School Time: Hours spent in formal educational settings. * Enrichment Activities: These encompass out-of-school pursuits aimed at enhancing intellectual development. Examples include reading, completing homework, engaging with board games, or learning a musical instrument. * Screen Time: Time spent using electronic devices such as televisions, computers, tablets, and smartphones. * Physical Activities: Time engaged in active pursuits.
To ensure robust comparisons, the diaries of firstborn children were analysed against those of later-born children. The study carefully matched these groups based on several factors, including birth year, geographical neighbourhood, and socioeconomic background. All families included in the comparison had either two or three children. While direct sibling comparisons within the same family, across identical ages and time periods, were not feasible due to data limitations, the researchers noted that previous studies on different outcomes (like academic achievement) have shown that birth order comparisons across different families yield very similar results to within-family comparisons, especially when family size is accounted for, as it was in this study. This suggests the findings are likely to reflect actual sibling dynamics.
Younger Siblings Clock More Screen Time, Less Enrichment
The study's findings paint a clear picture: later-born children tend to spend more time in front of screens than their older siblings. Specifically, secondborn children averaged an extra nine minutes of screen time per day, while thirdborn children spent an additional 14 minutes. While these figures might seem modest on a daily basis, they represent a significant increase of 7–10% compared to the average daily screen time of firstborns. Cumulatively, this amounts to an extra one to 1.5 hours of screen time per week.
This increased screen engagement comes at a cost. Later-born children dedicated 11 to 18 minutes less per day to enrichment activities, a reduction of 11–20% compared to their older siblings. Interestingly, no consistent differences were observed between older and younger siblings in terms of time spent on other activities, such as schoolwork, physical exercise, or sleep.
The impact of birth order appeared to be more pronounced among older children, particularly those aged 10–14. This observation suggests that early adolescence is a critical period where these differences in time allocation may become more significant and warrant particular attention. To ascertain if these patterns were unique to Australia, the researchers replicated the analysis using time-use diaries from children in the United States. The results mirrored those found in the Australian sample, indicating a broader trend.
Why the Discrepancy? Exploring the Driving Forces
A common explanation for these observed differences centres on parental time. As families grow, parents may have less time and individual attention to dedicate to fostering the development of subsequent children. However, the study suggests this might not be the sole factor.
While later-born children did spend less time on enrichment activities with their parents, a substantial portion of this difference – approximately half – stemmed from later-born children engaging in fewer enrichment activities on their own. A similar trend was observed with screen time. The increase in screen usage among later-born children was largely attributed to activities they undertook independently, rather than in the company of parents or siblings. This indicates that children's own choices and opportunities play a significant role, not just direct parental involvement. For instance, a younger sibling might have more autonomy to choose to play video games over completing homework.
Despite this, parenting practices likely still play a crucial role. The research found that later-born children tend to face fewer restrictions regarding screen use, such as limits on specific programs or overall time. They were also less likely to perceive that their parents expected them to adhere to such rules. This could, in part, reflect a parental desire to maintain a sense of fairness, allowing siblings similar screen access rather than imposing age-specific limitations.
The Long-Term Implications and What Can Be Done
The daily differences in time allocation uncovered by this study, while seemingly small, can accumulate significantly over time. As previous research from 2024 has indicated, increased screen time coupled with reduced engagement in activities like reading, homework, and other learning pursuits can lead to discernible gaps in academic skill development throughout childhood, as evidenced by lower standardised test scores.
The rise in solo screen time for later-born children is particularly concerning due to the potential for exposure to inappropriate online content.
Recognising these patterns is the first step towards developing more effective parenting strategies. Understanding that later-born children, on average, spend more time on screens and less time on enrichment activities than their firstborn counterparts can help parents tailor their approaches.
Secondly, prioritising quality time with later-born children, actively encouraging enrichment activities, and consistently enforcing rules around screen time are vital. These actions can help to counterbalance the observed trends.
Finally, the findings suggest that broader societal policies, such as implementing social media limits for individuals under 16, could play a role in levelling the playing field. Such measures could help to ensure that all children, regardless of their birth order, have equitable opportunities to learn, grow, and develop to their full potential.
