Understanding: Billboard BB200 vs US Album Sales

2017 - Japan - Naha Okinawa - Public Market - 13 of 21

I) Establishing Key Formulas

A) The Market Size

You don’t need to follow charts carefully to know that hitting #1 or the Top 10 in 1965, 1985 or 2005 isn’t the same thing. The market evolves constantly with album sales varying a lot over spans of several years. The number of albums sold per year in the US are known since 1973 thanks to this RIAA page. For the years prior we needed to go through Billboard history to identify the edition from each year that reported the new market numbers when they came out. Some of them detail figures in gross only rather than units, but that was converted thanks to the prices in place at the time.

It starts to look difficult – don’t be afraid, I did this job for you!

No real surprise here with a dreadful market by 1962 that increased consistently almost every year until 1980. Then came the first crisis of the music industry during the first half of the 80s. From 1987, the market recovered and the new boom thanks to the arrival of the CD started.

Those market figures will enable us to put a factor that will adjust our charts-to-sales conversion formula depending on the period. We also need to convert positions into sales, this is the second phase…

    1. Hi Gus!

      Obviously you are correct, I always think about Kenny G when talking about Michael Bolton and vice versa, don’t ask me why! Now fixed 😉

  1. Hello dear MJD it’s really a very interesting article on RIAA certifications.
    From this article it is evident that some artists such as U2 or Michael Jackson were massively inflated.
    This fact will affect on global sales ? For example the U2 in last year’s article have sold about 192.400.000 equivalent album sales with 12x platinum for The Joshua Tree, 8x platinum for Achtung Baby, 5x platinum for Rattle and Hum and War etc..
    Based on this new article for example their US album sales and their world album sales will be lower ?

    1. Hi Anthony,

      No, it doesn’t impact RIAA certifications. Their awards were achieved thanks to catalog sales and CSPC articles took that into consideration already!

  2. Great job man! Are we getting the 2nd part of your Understanding article about download sales vs. streaming? This is the one I’m most excited about, haha.

  3. Hey MJD,
    You’ve done a lot of work on 90’s and 2000’s artists and I think you should consider looking at Ashanti’s discography. She came out with a strong debut and had hit songs in her time

    1. Hi Luca!

      The factor can be easily calculated for post-1990 years using US Sales Database. I avoided it on purpose for two reasons:
      – Soundscan reflects better ups and downs, runs are much less linear, which corrupts the grouping of positions logic. In the past, a standard run was 152-81-55-38-33-32-33-39-60-121-155-187-out. Now you can have 10-39-101-199-out, which would give a much better result than 11-41-101-out.
      – Internet/pre-orders: they massively frontloaded sales which means now a #1 can sell 30k or 1m. This completely corrupts every possible calculation!

  4. Hi MJD!

    Forgive me for being quite ignorant, but I’ve re-read your article a thousand times, and I still don’t know how you input the Xmas factor in your calculations. I know how to calculate without the Xmas factor, but how do you add in the Xmas factor? Does it depends on which positions it charted during December?

  5. Hi MJD!

    Forgive me for being ignorant, but I still don’t know how you add in the Xmas factor in your calculations. Could you elaborate on how to do that?

    1. Hi Raffi!

      You are two that did this comment (with someone at SHF) so I suppose this part is unclear, I’ll amend the text! In the meantime, here is the answer I made to the other comment:
      The Xmas factor ais roughly the same scale as the chart overall, just slightly lower. Here is the weight you should give to an album depending on its average ranking in December:
      At #1 = weight 15 to 20 (depending on how big it was / how long it remained at 1)
      Charting 2-5 = weight 12
      Charting 6-10 = weight 8
      Charting 11-20 = weight 6
      Charting 21-40 = weight 4
      Charting 41-100 =weight 2
      Charting 101-200 = weight 1
