Red, Asia. 39 00:01:33.420 --> 00:01:37.020 Yellow, Europe. And green, the Americas. 40 00:01:37.020 --> 00:01:39.270 Vertical is child mortality. 41 00:01:39.270 --> 00:01:42.870 From 30% of children dying before the age of five, 42 00:01:42.870 --> 00:01:45.450 down to almost zero child death. 43 00:01:45.450 --> 00:01:48.900 Horizontal, number of babies born per woman. 44 00:01:48.900 --> 00:01:51.570 From eight to less than two. 45 00:01:51.570 --> 00:01:53.370 But most countries were up here. 46 00:01:53.370 --> 00:01:55.860 Women had six to seven children. 47 00:01:55.860 --> 00:01:57.720 Child deaths were frequent. 48 00:01:57.720 --> 00:02:01.890 Almost every family lost one or more children. 49 00:02:01.890 --> 00:02:03.390 In many people's mind, 50 00:02:03.390 --> 00:02:05.550 the world still looks like this: 51 00:02:05.550 --> 00:02:07.530 developing and developed. 52 00:02:07.530 --> 00:02:09.810 But it's a myth because the world 53 00:02:09.810 --> 00:02:12.930 has improved immensely in the last 50 years. 54 00:02:12.930 --> 00:02:14.280 Here we go. 55 00:02:14.280 --> 00:02:16.650 Year by year, child mortality fell 56 00:02:16.650 --> 00:02:18.150 in almost all countries. 57 00:02:18.150 --> 00:02:19.920 And as child mortality failed, 58 00:02:19.920 --> 00:02:22.170 women chose to have fewer and fewer babies, 59 00:02:22.170 --> 00:02:24.930 and that enabled them to invest more time 60 00:02:24.930 --> 00:02:26.583 and resources in each child. 61 00:02:27.510 --> 00:02:31.890 By 1990, some of the so-called developing countries 62 00:02:31.890 --> 00:02:34.590 had already made it down here. 63 00:02:34.590 --> 00:02:36.720 Some were in-between, 64 00:02:36.720 --> 00:02:40.770 and a few remained up here with very high child mortality. 65 00:02:40.770 --> 00:02:42.720 Ethiopia had hardly moved at all. 66 00:02:42.720 --> 00:02:44.520 It had passed through decades 67 00:02:44.520 --> 00:02:47.310 of famines and political turmoil. 68 00:02:47.310 --> 00:02:50.940 Many people think that Ethiopia is still stuck up here. 69 00:02:50.940 --> 00:02:53.790 But look what happens after 1990. 70 00:02:53.790 --> 00:02:55.680 With improved access to health service 71 00:02:55.680 --> 00:02:57.840 in rural areas and well-spent aid, 72 00:02:57.840 --> 00:03:00.750 child mortality falls dramatically in Ethiopia. 73 00:03:00.750 --> 00:03:02.940 And with better access to family planning, 74 00:03:02.940 --> 00:03:05.670 women choose to have fewer and fewer babies. 75 00:03:05.670 --> 00:03:07.890 Ethiopia has come halfway 76 00:03:07.890 --> 00:03:10.740 and is moving quickly down to this corner. 77 00:03:10.740 --> 00:03:14.160 But Ethiopia still faces many challenges. 78 00:03:14.160 --> 00:03:16.620 I will split the Ethiopian bubble. 79 00:03:16.620 --> 00:03:20.730 The capital, Addis Ababa, is already down here. 80 00:03:20.730 --> 00:03:23.970 But the remote Somali region of Ethiopia 81 00:03:23.970 --> 00:03:26.340 still have high child mortality. 82 00:03:26.340 --> 00:03:28.440 But most of the regions, 83 00:03:28.440 --> 00:03:32.490 90% of the population are centered around the average. 84 00:03:32.490 --> 00:03:34.020 Most people think that the problems 85 00:03:34.020 --> 00:03:36.030 in Africa are unsolvable, 86 00:03:36.030 --> 00:03:38.160 but if the poorest countries can 87 00:03:38.160 --> 00:03:40.470 just follow the path of Ethiopia, 88 00:03:40.470 --> 00:03:42.600 it's fully possible that the world 89 00:03:42.600 --> 00:03:45.870 will look like this in 2030. 90 00:03:45.870 --> 00:03:49.800 Then, there will be no countries left in the box 91 00:03:49.800 --> 00:03:52.890 we once called the developing world. 92 00:03:52.890 --> 00:03:55.050 But to ensure that that happens, 93 00:03:55.050 --> 00:03:58.320 we must measure the progress of countries. 94 00:03:58.320 --> 00:04:00.180 It's only by measuring, 95 00:04:00.180 --> 00:04:02.883 we can cross the river of myths. 96 00:04:05.490 --> 00:04:07.170 So that's Hans Rosling 97 00:04:07.170 --> 00:04:09.420 being classic Hans Rosling. 98 00:04:09.420 --> 00:04:12.000 And you think about the data here, 99 00:04:12.000 --> 00:04:13.350 we only have four variables, right? 100 00:04:13.350 --> 00:04:16.170 Child mortality, babies, born per woman, okay. 101 00:04:16.170 --> 00:04:18.990 We have population size. That's the bubble size. 102 00:04:18.990 --> 00:04:20.040 He doesn't even talk about that. 103 00:04:20.040 --> 00:04:21.900 But it helps us track like India and China, 104 00:04:21.900 --> 00:04:23.790 a couple of the bigger countries. 105 00:04:23.790 --> 00:04:26.310 And then, we also have the continents, right? 106 00:04:26.310 --> 00:04:29.850 Just the color to show us Africa, Asia, et cetera. 107 00:04:29.850 --> 00:04:34.500 But underlying that is very complex data, right? 108 00:04:34.500 --> 00:04:37.950 We have 8 billion people on Earth today. 109 00:04:37.950 --> 00:04:41.310 50 years ago, 60 years ago now almost, 110 00:04:41.310 --> 00:04:42.150 how many were there? 111 00:04:42.150 --> 00:04:43.710 5 billion? 6 billion? 112 00:04:43.710 --> 00:04:45.780 Whatever it is, times 50 years, 113 00:04:45.780 --> 00:04:47.430 whatever the average is. 114 00:04:47.430 --> 00:04:49.860 You know, we're talking about many, many, 115 00:04:49.860 --> 00:04:51.870 many, many data points, right? 116 00:04:51.870 --> 00:04:54.960 We're talking about very sophisticated statistics 117 00:04:54.960 --> 00:04:57.240 to really understand even these two simple variables, 118 00:04:57.240 --> 00:04:58.263 four, really, 119 00:04:59.370 --> 00:05:00.840 and how they've changed over time, 120 00:05:00.840 --> 00:05:02.250 and especially the projections 121 00:05:02.250 --> 00:05:05.880 of what it might look like by 2030. 122 00:05:05.880 --> 00:05:09.390 So serious underlying math and statistics going on. 123 00:05:09.390 --> 00:05:12.570 But he explains it very, very clearly, 124 00:05:12.570 --> 00:05:14.557 and he doesn't just throw a chart at us and say, 125 00:05:14.557 --> 00:05:16.470 "Good luck. Hopefully, you'll understand it." 126 00:05:16.470 --> 00:05:18.150 Or have a paragraph of text explaining 127 00:05:18.150 --> 00:05:20.490 sort of the meaning without really walking us through it. 128 00:05:20.490 --> 00:05:23.520 No, he explains it in a story. 129 00:05:23.520 --> 00:05:26.850 And the story, the narrative, flows really nicely. 130 00:05:26.850 --> 00:05:29.040 And Ethiopia is an example 131 00:05:29.040 --> 00:05:30.840 that he sort of brings up 132 00:05:30.840 --> 00:05:33.390 to really illustrate the idea behind this story. 133 00:05:33.390 --> 00:05:34.740 And he even gets into the nuance 134 00:05:34.740 --> 00:05:36.007 of Ethiopia to explain that, 135 00:05:36.007 --> 00:05:38.340 "Listen, it's not all black and white, right?" 136 00:05:38.340 --> 00:05:39.930 So, why are we here? 137 00:05:39.930 --> 00:05:41.970 That was where we started this question, right? 138 00:05:41.970 --> 00:05:44.460 We are here because we want to be more like Hans. 139 00:05:44.460 --> 00:05:46.380 We want to work to take 140 00:05:46.380 --> 00:05:49.140 what may be very complex underlying data, 141 00:05:49.140 --> 00:05:50.760 and find insights in it. 142 00:05:50.760 --> 00:05:52.950 Not that we're teaching how to find the insights much, 143 00:05:52.950 --> 00:05:54.390 a little bit last week. 144 00:05:54.390 --> 00:05:55.470 But then, most importantly, 145 00:05:55.470 --> 00:05:57.660 for our purposes in this class, 146 00:05:57.660 --> 00:05:59.640 to then take those insights 147 00:05:59.640 --> 00:06:01.950 and communicate them to audiences. 148 00:06:01.950 --> 00:06:04.290 Get our audiences to understand, 149 00:06:04.290 --> 00:06:06.720 really connect with that information, 150 00:06:06.720 --> 00:06:08.190 so they can do whatever they're supposed to do with it. 151 00:06:08.190 --> 00:06:09.900 Maybe they're just supposed to learn something. 152 00:06:09.900 --> 00:06:12.630 Maybe they're just supposed to teach it to others. 153 00:06:12.630 --> 00:06:13.890 Maybe they're supposed to take some sort 154 00:06:13.890 --> 00:06:15.360 of action based on it. 155 00:06:15.360 --> 00:06:16.470 Whatever it is, 156 00:06:16.470 --> 00:06:19.740 great data communicators can really do that. 157 00:06:19.740 --> 00:06:21.543 So that's why we're here.
