Worldwide spending on mobility solutions is forecast to reach $1.72 trillion in 2021, according to new data from IDC (www.idc.com).

Although annual growth is expected to slow over the 2016-2021 forecast period, the research group still expects spending on mobility-related hardware, software, and services to see a five-year compound annual growth rate (CAGR) of 2.7%. Worldwide mobility spending will total $1.58 trillion in 2017, an increase of 4.3% over 2016.

The United States will account for nearly one quarter of all mobility spending throughout the forecast, making it the largest geographic market at nearly $392 billion in 2021. Mainland China will be the second largest country in terms of overall spending ($337 billion in 2021), followed by Japan, Brazil, and the UK. The countries that will see the fastest growth in mobility spending over the five-year forecast period will be Venezuela (8.2% CAGR), India (8.0% CAGR), Philippines (7.0% CAGR) and Peru (6.7% CAGR). In contrast, four countries (Australia, Israel, Saudi Arabia, and Taiwan) are forecast to experience a slight decline in mobility spending.

Consumers will provide more than 70% of total mobility spending for all but the last year of the forecast, according to IDC. Most of this spending will go toward mobile connectivity services and smartphones. In addition to being the largest source of spending, the consumer sector will also experience the slowest growth with a five-year CAGR of 1.3%.

Banking and professional services will be the two industries with the largest mobility spending over the forecast period, reaching $55.1 billion and $54.9 billion in 2021, respectively. Discrete manufacturing and retail will be close behind with 2021 outlays of $49.7 billion and $45.7 billion. The industries with the fastest growth in mobility spending will be professional services (7.5% CAGR), construction (7.1% CAGR), and telecommunications (7.0% CAGR). Four other industries (federal/central government, healthcare, retail, and security and investment services) will also outpace the overall market, each with a 6.9% CAGR.
