Delivery density refers to the number of deliveries made in a specific geographic area within a given time frame. High delivery density is easier to manage in urban environments, but in low-density areas, particularly rural or suburban regions, last mile delivery becomes inefficient and costly. To overcome these challenges, businesses are utilizing data analytics to consolidate deliveries and improve route efficiency. Partnering with local couriers or using distribution hubs can also help reduce delivery times and costs in low-density areas.
