00:00:00,240 --> 00:00:05,200
hello everybody this is a video in which I'm gonna show you how to draw a

2
00:00:05,200 --> 00:00:11,919
population pyramid taking into account a table with data and you will have to do

3
00:00:11,919 --> 00:00:17,160
a similar one for the next week but it's gonna be really easy and I will ask you

4
00:00:17,160 --> 00:00:23,039
to analyze some data sorry for any inconvenience I know that the light is

5
00:00:23,039 --> 00:00:28,480
not the most appropriate but it's nothing I can do let's going to start

6
00:00:28,480 --> 00:00:35,479
them right here the first thing that we have to take into account is that we

7
00:00:35,479 --> 00:00:41,799
have three columns one column and one column shows me the age of the people

8
00:00:41,799 --> 00:00:48,700
living in that place and the other ones are showing me if the inhabitants are

9
00:00:48,700 --> 00:00:56,439
men or women right another aspect that we have to take into account is that the

10
00:00:56,439 --> 00:01:08,500
8 is ranging from 5 to 5. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, right? And let's going to start

11
00:01:08,500 --> 00:01:23,489
drawing our pyramid. I will need first to draw two parallel lines and I will

12
00:01:23,489 --> 00:01:40,060
draw a perpendicular line. And now we are going to start pulling the 8. We said

13
00:01:40,060 --> 00:02:13,520
that it ranges from 5 to 5 so 0 4 5 9 10 14 15 19 20 24 30 34 35 39

14
00:02:13,520 --> 00:02:44,560
49, 40, 44, 45, 49, 50, 54, 59, 54, 55, 59, 60, 65, 69.

15
00:02:44,560 --> 00:02:55,860
and as you can see here I have 70 and more right so this is the first thing I

16
00:02:55,860 --> 00:03:00,919
have to do because the other way it will be really difficult to draw it and you

17
00:03:00,919 --> 00:03:07,060
will be lost right the second aspect I have to take into account is that I will

18
00:03:07,060 --> 00:03:15,120
have a bigger number a biggest number on it right so if I observe I hear 11 now

19
00:03:15,120 --> 00:03:25,139
and 83 is for the moment my biggest name so I will take it into account and now I will analyze the

20
00:03:25,139 --> 00:03:35,580
woman and I will say that yes is 83 so here I will have to reach at least to 83 right so how can I do

21
00:03:35,580 --> 00:03:44,039
do it I can divide it into lines ranging from ten to ten for instance I have I

22
00:03:44,039 --> 00:03:52,259
will need a nine lines right one two three four five six no smaller right it's

23
00:03:52,259 --> 00:04:01,889
something that you have to take into account six seven eight and nine very

24
00:04:01,889 --> 00:04:15,930
So 1, 2, 3, 4, 5, 6, 7, 8, 9. Perfect. So now I can start. So ranging from 0 to 4 I have,

25
00:04:15,930 --> 00:04:26,050
and where do I have to put the women and the men? So as you read on the theory,

26
00:04:26,050 --> 00:04:32,149
men's are gonna be in that part and women are gonna be in this one right so

27
00:04:32,149 --> 00:04:46,329
men so from 0 to 4 I have 11 this is 10 remember 10 20 30 40 50 60 70 80 90

28
00:04:46,329 --> 00:04:54,790
right and the other way in the other size we will do the same so I have

29
00:04:54,790 --> 00:05:13,889
11 and I know it from 5 to 9 I have 15 so yes from 10 to 14 I have 19 almost 20

30
00:05:13,889 --> 00:05:24,129
so it must be here right 23 is the next one right

31
00:05:24,129 --> 00:05:34,870
23 and from 20 to 24 i have 24 people one less

32
00:05:34,870 --> 00:05:42,560
25 to 29 i have uh 28 25

33
00:05:42,560 --> 00:06:16,680
38, 30, 34 is 40, help yourself, right, 35, 39 is 50, so 40, 44 is 48, 48, here I have

34
00:06:16,680 --> 00:06:51,800
40, again 40, 39, 53, so 50 is here, more, 53, 65, and 83, so 80 is here, more than 80, 83.

35
00:06:52,800 --> 00:06:57,259
This is part of my pyramid. Let's go to continue with the other side.

36
00:06:57,259 --> 00:07:16,240
I'm gonna change the color so you will see the difference so I have 12 this is 10 20

37
00:07:16,240 --> 00:07:38,790
70 80 and 90 right so a 10 12 sorry 10 and two more 12 12 13 21

38
00:07:38,790 --> 00:09:18,649
20, 25, 7, 41, 40, 41, 48, almost, maybe a little bit less, 40, 44, 41, 40, 38, 38, 51, 65, and 81.

39
00:09:19,990 --> 00:09:41,059
Right, so here I have the pyramid of the place I have chosen for this activity.

40
00:09:41,059 --> 00:09:47,059
What can we know about it? First, we can know that is an inverted pyramid.

41
00:09:47,059 --> 00:09:56,059
That means that I have more elder people than young people.

42
00:09:56,059 --> 00:10:21,960
right? That means that in 30 years, for instance, if you now are 10 years old, in 30 years you will be 40 years old and I have my pyramid, I will have a lot of elder people but I won't have young people or people who are in age in which they can't work, right?

43
00:10:21,960 --> 00:10:40,799
So what else can I learn from it? That the population is decreasing because I have older people but I don't have young people, I don't have kids on that place, right? So those are some aspects that we can know just analyzing our parents.

44
00:10:40,799 --> 00:10:49,440
so what you have to do is doing the same as i have done but uh with different data right

45
00:10:50,080 --> 00:10:57,759
and that's all if you have any doubts email me and i will ask you bye thank you
