Two figures, two measuresThe 1940s and the early 1990s

By the 1940s, more than half of the nation’s rose bushes were grown within ten miles of Tyler.¹By the early 1990s, fewer than 50 Texas growers produced 8 to 10 million bushes a year, 16 to 20 percent of the U.S. crop.²

: “More than”: the source gives no upper figure

The same figures, as a table

They count different things: rose bushes within ten miles of Tyler as a share of the nation’s, and the bushes of fewer than 50 Texas growers as a share of the U.S. crop. No figure for the decades between appears in these sources, so the two are never joined by a line.

Two figures for Tyler’s roses, with what each measures
When	Figure	What it measures
By the 1940s	More than half	Rose bushes grown within ten miles of Tyler, as a share of the nation’s rose bushes
1950 to 1989	No figure	None in these sources
By the early 1990s	16 to 20 percent	The bushes of fewer than 50 Texas growers (8 to 10 million a year), as a share of the U.S. crop

A third figure measures something else again: in 1945 Smith County produced 80 percent of the Texas rose crop.³

Tyler no longer grows half the nation’s roses; the local industry has since shifted largely from growing roses to processing them.⁴

Notes

By the 1940s, more than half of the nation’s rose bushes were grown within ten miles of Tyler.
This is a figure for the 1940s, not for today.

The share is of the Texas crop, as the Handbook of Texas words it, not of the nation’s.
