Coverage
Our United States RDD sample connects with 320 million individuals for your research.
In the United States, mobile phones have become increasingly popular in recent years, leading to a decline in the use of traditional landline numbers. According to a report by the Centers for Disease Control and Prevention, in 2018, approximately 53% of American households relied solely on mobile phones, compared to just 6.5% that used only landline numbers. This shift towards mobile usage can be attributed to the convenience and mobility offered by smartphones, as well as the declining costs of mobile plans. Furthermore, a study by the Pew Research Center found that 96% of Americans own a cellphone of some kind, with 81% owning a smartphone. The widespread adoption of mobile phones has led to a decrease in the importance of landline numbers for communication purposes. However, landlines are still commonly used in certain industries, such as businesses and healthcare, where a reliable and secure connection is essential. Overall, the data suggests that mobile phones are more frequently used than landlines in the United States, signaling a greater reliance on wireless communication in the modern age.
