In the first part of this series I discussed the effects of the Industrial Revolution on employment. In this segment I’ll conduct a similar analysis of the Digital Revolution. For purposes of this discussion by “Digital Revolution” I mean the widespread adoption of computers which I would reckon as between 1983 and the present. The reason I pick 1983 as the start of the Digital Revolution is that the IBM PC had been introduced in 1981. IBM’s dominance gave corporations permission, as it were, to use personal computers but there were three developments in 1983 that supercharged the adoption of personal computers. One was the introduction of the IBM XT, a substantial enhancement to the PC, a second was the release of Lotus 1-2-3, the first “killer application” on the IBM PC/XT, and the introduction of the Apple IIe which I would mark as the predecessor of the Mac.
There are reasonable alternative start dates for the “Digital Revolution”. In the 1960s the penetration of computers was largely limited to the largest companies. The ARPAnet, the prototype Internet, was limited to colleges, government, and a few laboratories when it was introduced in the 1970s. I think the real start date is when desktop computers and their “killer apps” took root in the economy and the society.
I want to emphasize that in this post I am going to focus on the effect of the Digital Revolution on work in the United States not globally. While the global impact may be even more important than the impact on work in the U. S. it is beyond the scope of this post.
As I noted the Industrial Revolution shifted substantial numbers of jobs from agriculture to industrial sectors but that is not its most significant effect. It actually changed the nature of work, from primarily agriculture to primarily manufacturing and services.
The Digital Revolution has
- eliminated many routine/manual jobs and reshaped service and clerical roles
- created new digital and tech-enabled occupations
- changed the nature of work dramatically
Jobs Eliminated
The Digital Revolution has resulted in the elimination of 7 to 12 million jobs, particularly in
- manufacturing
- clerical/administrative support
- retail support roles
- routine bookkeeping and office jobs
- telephone operators and related categories
In 1983 U. S. manufacturing employment was roughly 17 million; it is roughly 13 million at present. A substantial share of those jobs were lost to automation and digitization. It was not completely due to offshoring although the Digital Revolution facilitated offshoring of manufacturing jobs but any discussion of that is beyond the scope of this post.
Between 1983 and the present almost 4 million clerical jobs were eliminated, largely having been automated by word processors, spreadsheets, and database programs. When I started working, roughly sixty years ago even small companies employed clerk typists, bookkeepers, and other clerical workers.
Approximate clerical job losses since 1983
| Category |
Jobs eliminated |
| Secretaries/typists |
~1.4 million |
| Bookkeepers/accounting clerks |
~1.2 million |
| Switchboard/telecom operators |
~0.25 million |
| File clerks, mailroom, clerical support |
~0.8 million |
or a reduction of about 3.6 million clerical jobs.
Digitization in the form of scanners, point-of-sale terminals, inventory automation, and eCommerce has also affected jobs in retail. According to the Bureau of Labor Statistics that has eliminated between 1.2 million and 1.5 million retail support and cashiers’ jobs.
There has also been a decline in transportation jobs and jobs in printing/publishing due to digitization of about a half million.
All told it is estimated that between 7 and 12 million jobs have been eliminated as a consequence of the Digital Revolution.
Jobs Created
Like the Industrial Revolution before it the Digital Revolution has created more jobs than it has eliminated. It is, however, difficult to estimate how many jobs have been created because they are distributed across the economy.
In the technology sector 7 to 8.5 million jobs have been created consisting of the 5 to 5.6 million jobs created in software publishing and the information technology sector, the .5 million to 1.5 million jobs in telecommunications and Internet services, and the .5 million to 1 million jobs created in electronics, semiconductor, and computer hardware.
In eCommerce, logistics, warehousing, and distribution 5 million jobs have been created consisting of more than 2.5 million jobs in warehousing and fulfillment, more than 1.5 million in parcel delivery and logistics coordination, and more than 1 million in eCommerce corporate and operational roles.
Something like 3.5 million to 5 million jobs have been created in professional services that did not exist prior to the Digital Revolution including digital marketing, cybersecurity, data science, IT consulting, computer-aided healthcare roles, and business services based on analytics.
Finally, something like 3.5 to 4 million jobs have been created in the gig economy, creator economy, and remote digital freelancers.
These categories are not mutually exclusive, and some overlap is unavoidable; the purpose here is to establish scale rather than produce a perfectly partitioned taxonomy.
All told 15 to 20 million jobs have been created in the United States as a consequence of the Digital Revolution.
Discussion
In 1983 there were roughly 93 million jobs in the U. S. By 2023 there were something like 156 million jobs in the U. S. for an increase of something like 64 million jobs. A reasonable guesstimate is that the Digital Revolution accounts for about 25–30% of all new jobs in that period. The jobs eliminated were mostly highly routine and more jobs were created than destroyed. The jobs eliminated were overwhelmingly located in the U. S. while the jobs created were both in the U. S. and offshore. The jobs in the section above are U. S.-located jobs only. In addition millions of jobs were created offshore but that is a topic for another post. The bottom line is that the Digital Revolution replaced millions of Americans doing routine tasks
with millions of foreign workers performing new digital tasks and millions of domestic workers performing new nonroutine tasks.
That was not entirely benign. Middle-skill jobs fell sharply. High-skill jobs rose sharply. Low-skill service jobs rose somewhat. The offshoring of jobs resulted in creating a wage ceiling on IT wages at all but the topmost levels, back-office administrative jobs, and telephone support wages. That in turn tended to increase income inequality in the U. S. There were other causes as well but that, too, is beyond the scope of this post.
There is another important difference between the Industrial Revolution and the Digital Revolution which is the pace of the change. The Industrial Revolution in the United States took place over something between a century and a century and a half while the Digital Revolution has taken place over about a 40 year period, in one working lifetime. This compression of disruption into a single working lifetime sharply constrained the ability of educational institutions, labor markets, and political systems to adapt.
In the next post in this series I will discuss the present Artificial Intelligence Revolution.
