The median age sits around 30 years, with many households composed of couples with children and an average of three persons per dwelling.

Bus links connect Middleton Grange to Liverpool train station and surrounding suburbs, but the suburb lacks a direct rail connection.
Infrastructure in the suburb includes recycled water systems and substantial council investment in roads and utilities as part of ongoing development since its proclamation in 2005.
Educational facilities encompass two established schools: Middleton Grange Public School (opened 2009) and Thomas Hassall Anglican College (since 2000), catering to early learning through Year 12.
The suburb contains local parks, comprising around 28.7 per cent of its 2.5 km² area, including playgrounds and green spaces for recreation.
Additional amenities such as medical centres, childcare services, restaurants and commercial offices are either established or under development in line with council recommendations.
Major shopping options, hospitals and higher-order services like cinemas and major retail lie a short drive away in Liverpool, adjacent suburbs such as Carnes Hill and Hoxton Park.
