The United Nations agreed last year that everyone, even in the least developed countries, should have Internet access by 2020. However, according to a study by the Alliance For Affordable Internet (A4AI), the world is currently likely to miss that target.

By how much? More than two decades. According to A4AI, whose members range from Google GOOG and Facebook FB to the World Wide Web Foundation and several governments, universal access will only become a thing in 2042, if we keep going at the pace we’re going.

Here’s what the alliance said in its report, released at the start of Mobile World Congress in Barcelona:

Without urgent reform, in 2020 we will see just 16% of people in the world’s poorest countries, and 53% of the world as a whole, connected. We won’t just miss the target, we’ll miss by a mile. This connectivity lag will undermine global development across the board, contributing to lost opportunities for economic growth and denying hundreds of millions access to online education, health services, political voice, and much, much more.

The current target here is for people to be able to get online for less than 5% of average incomes.

According to A4AI, income inequality is a big part of the problem — technically, just under half the countries covered in its report meet the target overall, but far fewer (nine out of 51) meet it for the bottom 20% of income earners. The gender wage gap means women are particularly unlikely to get online in much of the world.

The report recommends reforming tax and patent regimes to bring down the cost of phones (a pretty major factor in all this), increasing the available of public, subsidized Internet access and setting new targets to close the digital gender divide.

What’s more, the alliance wants a new, more ambitious affordability target: For people in even the poorest countries to be able to get 1GB of data each month for 2% or less of their average monthly income.

“This report must serve as a wake-up call to policymakers, business leaders and civil society everywhere,” said A4AI executive director Sonia Jorge in a statement. “If we are serious about achieving universal access by 2020, we need to condense almost 30 years worth of work into the next five years.”
