In 2019, a notable study published in the journal JAMA Pediatrics analyzed data from over 4 million children to explore the relationship between urban living and autism spectrum disorder (ASD). The study found a small but statistically significant association between living in a city and an increased risk of developing autism [1]. This association, however, is complex and influenced by various factors such as parental education, income, and ethnicity, which could confound the relationship.
Another study, published in the Journal of Autism and Developmental Disorders in 2018, examined the link between autism prevalence and population density across different states in the United States. This study also found that higher population density was associated with a greater prevalence of autism [1]. Nonetheless, it's crucial to clarify that these findings do not establish a causal relationship between city living and autism.
Population density appears to play a role in the prevalence of autism. The studies mentioned earlier indicate an increased prevalence of autism in densely populated areas. However, it is essential to consider other contributing factors such as environmental exposures, social stress, and access to healthcare services.
Studies have suggested that factors associated with urban living, like pollution, noise, and social stress, might contribute to an increased risk of autism [2]. For example, perinatal exposure to ambient air pollution has been consistently linked to a higher risk of ASD. Various aspects of air pollution, including hazardous air toxics, ozone, particulate matter, and traffic-related pollution, have shown compelling evidence for a potential causal association with autism [3].
Understanding the intricate relationship between urban living and autism requires considering multiple dimensions, including environmental exposures, social influences, and genetic factors.

Understanding the prevalence of Autism Spectrum Disorder (ASD) in different settings is crucial for addressing the needs of individuals with autism. This section examines the rates of ASD in rural versus urban areas, the challenges faced in rural settings, and the benefits of urban awareness.
Studies show similar rates of ASD prevalence in both rural (0.9%) and urban (1.0%) areas, indicating that the overall prevalence is not significantly different between these communities [4]. However, urban areas often report higher rates of ASD, sometimes over 2.5 times greater than rural areas, which suggests that densely populated areas have greater awareness and possibly better diagnostic resources.
Rural communities face unique challenges when it comes to diagnosing and managing ASD. Schools in these areas often serve as the primary mental health system for youth with autism. Parents in rural settings report lower rates of speaking to healthcare providers about their concerns compared to those in urban areas.
One significant issue is the lack of specialized professionals capable of identifying and treating higher-functioning individuals with ASD, particularly those without co-occurring intellectual or language impairments. This can lead to underdiagnosis and a lack of appropriate interventions. The need for improved resources and services tailored to rural communities is evident.
Urban areas, with their higher population densities, tend to have greater awareness of ASD. This higher awareness results in better diagnostic rates and a more robust support system for individuals with autism. Urban environments often provide easier access to specialized healthcare providers and intervention programs.
In addition, the availability of telehealth services is bridging the gap between urban and rural areas. Telehealth offers a cost-effective and time-efficient way for families in rural settings to pursue diagnosis and interventions for ASD. This approach is promising for delivering reliable, affordable, and convenient healthcare to hard-to-reach populations.

Access to autism services varies significantly between urban and rural areas. Schools in rural regions often serve as the primary mental health system for youth with Autism Spectrum Disorder (ASD). Parents in rural areas report lower rates of discussing their concerns with healthcare providers compared to their urban counterparts [4]. This disparity highlights the challenges faced by families in rural areas when seeking diagnosis and treatment for autism.
Rural areas may lack specialized professionals needed to identify and treat individuals with ASD, especially those with higher functioning and no co-occurring intellectual or language impairments. This gap in services can result in undiagnosed cases, delaying critical early interventions.
Telehealth services provide a promising solution to address the disparities in accessing autism services. Utilizing telemedicine and e-health platforms, families in rural areas can pursue diagnosis and interventions in a cost- and time-effective manner. These services have shown promise in delivering assessments and interventions to physically remote communities, overcoming the geographic barriers to accessing specialized care [4].
Telehealth offers several advantages:

Exploring the potential environmental risk factors for autism spectrum disorder (ASD) is crucial in understanding whether urban living could contribute to its development. This section delves into the roles of pollution, noise, and social stress in potentially increasing the risk of ASD.
Air pollution is a significant concern when evaluating environmental factors related to ASD. Exposure to air pollution, particularly during pregnancy, has been suggested as a possible risk factor for autism. Studies have shown that certain air pollutants, such as fine particulate matter (PM2.5) and nitrogen dioxide (NO2), may be associated with an increased risk of autism.
These pollutants can penetrate deep into the lungs and enter the bloodstream, potentially affecting fetal brain development. While the association between air pollution and ASD is compelling, further research is needed to establish a definitive causal link.
Noise pollution is another factor often associated with city living. Chronic exposure to high levels of noise can lead to stress and sleep disturbances, which may indirectly contribute to the risk of developing autism. Constant noise can affect a pregnant woman's stress levels and, consequently, fetal development. The relationship between noise pollution and ASD, while plausible, requires more empirical evidence to confirm any direct links.
Social stress is prevalent in urban environments due to factors such as high population density, competitive job markets, and fast-paced lifestyles. These stressors can impact both prenatal and postnatal development.
Social stress can manifest through:
The interplay between social stress and ASD risk is complex. Elevated stress levels during pregnancy can affect fetal brain development, potentially increasing the risk of autism. However, like pollution and noise, the direct impact of social stress on ASD development needs further investigation.

Understanding these environmental factors is essential for developing strategies to mitigate potential risks and providing better support for children with autism.
The level of urbanicity, or how urban an area is, has been studied in relation to the risk of Autism Spectrum Disorder (ASD). This section explores how the urban environment affects ASD risk from birth through childhood, as well as the impact of migration and early diagnosis trends.
Research has shown a dose-response association between urbanicity level and ASD, meaning that higher levels of urban living are linked to an increased risk of ASD. This association is observed not only at birth but also during childhood.
Children born in rural areas have the lowest risk of developing ASD, which may support the "hygiene hypothesis." This hypothesis suggests that exposure to allergens in rural environments can stimulate the immune system and potentially reduce the risk of disorders like ASD.
Postnatal migration, or moving to a different area after birth, has also been found to influence ASD risk. Children who move to a higher level of urbanicity after birth face an increased risk of developing ASD.
The risk is particularly notable for children who move from rural to urban areas, suggesting that environmental factors associated with urban living can significantly impact ASD development.
Urban areas have been found to be associated with an earlier age of ASD diagnosis compared to non-urban areas [3]. This may be due to better access to healthcare services, increased awareness, and more comprehensive screening programs in urban settings.
Early diagnosis is crucial for effective intervention and support. Urban settings often provide more resources and services for early diagnosis, which can be beneficial for children with ASD. For more information on the importance of early diagnosis, visit our article on what happens if autism is not treated?.
Understanding the relationship between urbanicity and ASD risk helps in identifying potential environmental factors that could influence the development of ASD. By recognizing these patterns, parents and caregivers can make informed decisions about their child's living environment and access to services.
