This Monday, the 1st April, 2 million people working minimum-wage jobs will start the week with a pay rise. The National Living Wage (NLW), the rate that applies to 25+ year olds, will rise by 38p, from £7.83 to £8.21. We project that this will increase the number of people paid at the wage floor to 2.7 million workers. In this article we chart the increasing reach of the minimum wage, and its impact on hourly wages at the bottom since its introduction in 1999.
First, who are the minimum wage employees? In 2019, 1.7 million are women (62 per cent of the total), and 1.6 million are working part-time (60 per cent of the total). Of course, there is significant overlap here – women working part time comprised more than two-in-five (43 per cent) of all minimum-wage workers in 2019. Minimum wage workers are also predominantly in the private sector (2.4 million in 2019 – 87 per cent of the total) and in three sectors in particular. In 2019, hospitality, wholesale and retail, and health and social Care together contain 3three-in-five minimum wage workers (58 per cent of the total).
On Monday the NLW enters its fourth year. The NLW is rising in value so that by October 2020 it will be equal to 60 per cent of median earnings (for those aged 25+), whereas in April 2015 it was worth 52 per cent. These increases are serving to extend the reach of the wage floor. In 2020, in just five years, the NLW will have doubled the proportion of employees paid the minimum from 6 per cent (representing 1.5 million workers) to 12 per cent (3.3 million workers).
The chart above shows the reach of the minimum wage across sub-groups of employees. It compares the coverage in 2015 (pre-NLW) with our projection of the reach in 2019 and 2020. Since Monday also marks the twentieth anniversary of the minimum wage’s introduction in the UK, we also look back to 1999. Perhaps most startling is the impact the minimum wage is now having in the three largest low-paying sectors (those mentioned above). By 2020, one-in-three workers in hospitality
will be paid the minimum wage. The policy is having a dramatic effect in that sector. In others, such as the public sector and finance, where pay is higher, the minimum wage has barely had any effect at all, and even the recent rises aren’t changing that.
The point of the minimum wage, of course, is to increase the wages of the lowest paid. The chart below shows that this goal has been achieved. Over the last twenty years, hourly pay growth has been strongest at the bottom of the distribution. The period after the policy’s introduction (1999 to 2003), is particularly striking, as is the impact of the recent NLW increases, with strong hourly wage growth for lower earners in the last three years. Monday’s uplift will see the NLW increase by 4.9 per cent, well above the current growth in average pay (in January the annual growth in average nominal weekly earnings was 3.4 per cent).
The debate has now turned to post-2020, with the Chancellor mooting an even more radical policy of ‘ending low pay’, which, based on the most widely used definition, would mean the minimum wage being set at 66 per cent of median earnings. This 66 per cent ‘bite’ would represent a leap into the unknown. Arin Dube’s review of minimum wages will help, but he will have scant international evidence to draw on for such a high bite. Of rich countries only France’s bite is comparable, and that’s only 62 per cent. What’s more, the differences between the two countries will make it hard to learn lessons directly. For example, in France most jobs are covered by collective bargaining arrangements, and there are extensive subsidies for employers hiring the low skilled and the young.
Still – the Chancellor’s ambition is laudable, and a far cry from back in 1999 when the Conservatives opposed the minum wage’s introduction. Today’s political consensus on the minimum wage is highly welcome. On its twentieth birthday, it is pleasing to reflect on how far the minimum wage has come. Where once it was seen as a job-killer, now the only question is ‘how high?’.
