excel - How can I transpose this data set into this specific order?

Question

I am using Excel 2016 and I have a data set with 492 rows and no headers. Data starts at Cell A1.

An extract of the data set looks like this:

I want to transpose this data set so that it becomes into this format:

I am new to VBA and I am having a hard time finding the right solution. I have tried recording the transpose as a Macro (step by step) and viewed the VBA codes but I still can't make it come together.

Try this code, but before you do adjust the two constants at the top to match the facts on your worksheet. The worksheet with the data must be active when the code is executed.

Sub TransposeData()

    Const FirstDataRow As Long = 2              ' presuming row 1 has headers
    Const YearColumn As String = "A"            ' change as applicable

    Dim Rng As Range
    Dim Arr As Variant, Pos As Variant
    Dim Rl As Long, Cl As Long
    Dim R As Long, C As Long
    Dim i As Long

    With ActiveSheet
        Cl = .UsedRange.Columns.Count - .UsedRange.Column + 1
        Rl = .Cells(.Rows.Count, Columns(YearColumn).Column).End(xlUp).Row
        Set Rng = Range(.Cells(FirstDataRow, YearColumn), .Cells(Rl, Cl))
    End With
    Arr = Rng.Value
    ReDim Pos(1 To (UBound(Arr) * UBound(Arr, 2)), 1 To 2)

    For R = 1 To UBound(Arr)
        For C = 2 To UBound(Arr, 2)
            i = i + 1
            Pos(i, 1) = Arr(R, 1)
            Pos(i, 2) = Arr(R, C)
        Next C
    Next R

    R = Rl + 5                                  ' write 5 rows below existing data
    Set Rng = ActiveSheet.Cells(R, YearColumn).Resize(i, 2)
    Rng.Value = Pos
End Sub
